My girlfriend and I are both 16. We talk a lot about sex and we also masturbate each other. Is that normal or should we worry? Does it mean we are lesbians? Should we tell our parents?

For girls who feel sexually attracted to girls it’s completely normal behaviour. Lesbians kiss and caress each other’s body and bring their lover to orgasm with their mouth or hand. I cannot tell whether you are a lesbian or not. Sexual behaviour does not necessarily reveal sexual orientation, especially during people’s teens, when it’s common to experiment. If you are a lesbian you’ll not be sexually attracted to guys and you’ll fall in love with girls. Give yourself time. You have to wait and see whether you prefer to have a (sexual) relationship with your girlfriend or with a guy. I would wait telling your parents about your sexual preference till you are sure about it yourself.
