Some girls experience pain the first time they have vaginal intercourse. They may have so much hymenal tissue that stretching it open during first intercourse may cause pain and bleeding. Girls with a lot of hymenal tissue can prepare for first intercourse by slowly stretching the tissue with their fingers.
For many people, “having sex” means engaging in a range of intimate, physical behaviors by yourself or with another person or persons that can often (but not always) involve the genitals. For some people, it’s only penis-in-vagina intercourse. For some people, it’s only penis-in-anus intercourse. For some people, it’s genital rubbing without intercourse. For some people, it includes oral/genital contact. For some it includes masturbation. The possibilities are many. For most of us, it includes all the above.
Anal sex can hurt if partners do not take certain steps. The anus does not usually produce enough lubrication for comfortable anal sex, so it’s important to use an artificial water-based lubricant — like K-Y jelly or Astroglide — for anal sex. (Using an oil-based lubricant, like Vaseline, can damage latex condoms.) Lubricants can make vaginal intercourse more comfortable as well.
It’s also important to stop doing it if anything hurts and communicate with your partner about how you feel — sex that’s painful or uncomfortable should not continue.
However you define it, being sexual with another person — whether that means kissing, touching, or intercourse — involves a lot of responsibility. It’s very important to protect yourself against pregnancy and STDs. And you need to make decisions about protection before you engage in vaginal, anal, or oral sex
