My partner and I just got diagnosed with Chlamydia, I been loyal to our relationship and she says the same thing, however there was a couple of times we had unprotected anal and vaginal sex within the same night, could this possibly be the source of the bacteria? Switching from anal to vaginal during intercourse?

Chlamydia can’t be transmitted by switching between vaginal and anal sex, although other infections can, so make sure you’re rinsing off in between and that both of you urinate after sex.

Chlamydia can take up to three months to show up in your system, so depending on your relationship history, one possibility is that one of you got it several months ago (perhaps from a previous partner) but it didn’t show up on an STI test until now. Chlamydia is transmitted through sexual contact with the penis, vagina, mouth, or anus of an infected partner.

What steps should a woman take before having anal sex?

First of all, condoms should be used during anal sex to help reduce the risk of STIs. The anus does not self-lubricate, so micro tears can occur easily in the anus. This can lead to a higher risk of STI transmission.

It is important to use lubrication when having anal sex. Like we previously mentioned, lubrication will help reduce the risk of the condom breaking as well as the occurrence of micro tears. It may also simply make things more comfortable. It is important to use water-based lubrication when using condoms. Any lubrication with oil (lotion, Vaseline, etc) can break down the material of the condom and make it ineffective.

You could also start slow by using fingers or toys first before engaging in anal sex to see what each person is comfortable with. Communicate with partner(s) if anything doesn’t feel good or is uncomfortable.

I had anal sex with my boyfriend…..

……and he came inside there. He kept thrusting and he accidentally slipped inside my vagina….is there anyway I could get pregnant?

Pregnancy is possible whenever semen enters the vagina. If semen accidentally got into the vagina during anal sex, then yes, there would be a risk for pregnancy. Or, if some of the ejaculate leaked from the anus to the vaginal opening, there would be a risk of pregnancy.


If you used a form of birth control, however, you would be protected from pregnancy. Depending on the method, you could be over 99% protected.

It is important to know that unprotected anal sex carries a high risk of STI transmission. This is because the lining of the anus is very fragile and does not self-lubricate. This makes it easier for micro tears to occur during intercourse. These micro tears are small and someone may not feel them. Micro tears can create a direct line to someone's blood and can therefore lead to STI transmission.


Using condoms during anal sex will reduce the risk of STI transmission. Using lubrication is also a good idea because lubrication helps reduce the risk of micro tears, and will help reduce the risk of the condom breaking.

I am a 14 year old male. I am gay, but I have told no one…I’m extremely scared to tell my parents or friends, in fear of rejection, or even being kicked out of the house, verbal abuse, etc. I am also wanting to create something safe for my body that I can use for anal masturbation, but I’m also worried about accidentally harming myself. I’ve lied on medical papers, marking them to say I’m straight in fear of my parents finding out I’m gay. What should I do?

Thank you for asking this. We want to address all of your questions one by one.

First, know that you are absolutely not alone in dealing with this. Also, there is nothing wrong with your sexuality. Who we like and who we're attracted to is part of what makes us who we are, and that is great!


Figuring out one's sexuality can feel scary and intimidating, especially if you feel like you have no one to talk to. Try thinking about someone you could confide in; someone you can trust. It could be a friend, a trusted adult, a sibling, etc. Try talking to that trusted person and see how it feels. This may give you confidence to talk to others.  It is likely that the people who love you, like your friends and family, want what is best for you! We do understand, however, that in some cases, a person may not feel safe sharing information like this with certain people. If this is the case, perhaps consider telling a counselor, prevention interventionist, or a teacher at your school. Those adults are there to help and support you.

If you live in the Boulder area, there is an organization called OASOS, they are a support group for LGBTQI youth.  You can find more information about them here or call them at 303-579-2676.

If you don’t live in the Boulder area, this is another great resource: :

If your school has a GSA (Gay Straight Alliance), perhaps reach out to people in that group to see how you can get support. Just know that there are people out there to help and support you.

In terms of when you visit the doctor, it is important to be honest on medical history forms. The reason that these forms ask for sexuality information is to better take care of you. If you live in Colorado, it is state law that teens can access sexual health services without the permission/notification of their parent/guardian. Alternatively, even if your parent/guardian is present, you have the right to keep your medical information just between you and your doctor.  If you do not live in Colorado, you can visit to find out your rights in your own state.

Regarding masturbation, it is completely healthy for people to explore masturbation. As long as it is not hurting you or anyone else and it is not interfering with other aspects of your life, it can be a healthy activity. There are sex toys that are designed specifically for anal play. This is important because the muscles in the anus squeeze involuntarily, which can pull objects into the anus. So if someone uses an item that does not have a flared base, it could potentially lead to a trip to the doctor to have it removed.

If you do not have access to sex toys, you could start with using your fingers. Finger stimulation can potentially provide pleasure, but make sure to wash your hands and use plenty of lubrication (the anus does not self-lubricate). You can buy lubrication over the counter, or usually can get some for free at health clinics.  Start slow,  make sure to trim your nails, and wear gloves or a condom on your fingers to prevent any infections or tears.

If you do live in Boulder and want to make an appointment at our Teen Clinic to further discuss any of these things you can call us at 303-442-5160, or you can walk in to pick up things like condoms or lubrication.
