Do I have to worry about STIs if I'm gay and don't have vaginal sex?
Unfortunately, STIs can be transmitted during ANY type of sex-- vaginal, oral, and anal. There are four specific modes of transmission: blood, sexual fluids, skin-to-skin contact, and vaginal birth. Since all types of sex can involve skin-to-skin contact and/or exposure to sexual fluids, STIs are a risk for anyone who's sexually active. We recommend dental dams for oral sex on either the vagina or anus as a barrier method to reduce transmission risk. You can find our more about them here. Also, remember that Teen Clinic offers free testing if you're 17 or younger!
I'm going to give my boyfriend a blow job and I don't know what I'm supposed to do at the end? I know guys like when you swallow but I don't want to get pregnant.
First of all, you should only ever do what YOU feel comfortable with and what you have consented to do, so if you don't feel comfortable swallowing the ejaculate, you should not do it. Secondly, you cannot get pregnant from swallowing ejaculate. Pregnancy can only happen when semen comes in contact with the vagina.
Remember that STIs can be transmitted during oral sex, so we encourage you and your partner to get tested and/or to use condoms to prevent STIs if there's a risk of transmission.
I gave a guy a blow job and some of his semen was on his hand at the end and then he fingered me. Is there a chance I could get pregnant??
The chances are low, but technically any time semen comes in contact with the vagina there is a chance of pregnancy (if you're not on birth control). If you want to be on the safe side, you can always take Plan B or another form of emergency contraception.
How do lesbians have sex?
It depends! Everyone has different preferences and experiences pleasure differently. Sometimes it involves touching using the hands/genitals/mouth, or sometimes people use various toys for stimulation. There is not a "right" way to do it.
