Some are of the school of thought that in as much as everyone is not bisexual, sexuality is fluid and as such people become bisexual at different stages in their lives; a phenomenon we now refer to as bi-curious. So if you're bi-curious you should explore that when you're ready. I just want to know what to do, and how to find out if I am bi. I realise we're not in high school anymore but some people do act this way. Anyway, you might be afraid of judgement because bisexuality or sexual fluidity is often associated with sexual promiscuity. So take this chance and go after it.
The fact of the matter is that closed-minded will people make assumptions about your sexuality if and when they find out.
What I mean is that you shouldn't do it just to say you've had the experience or because other people around you have done it or because you don't know until you've tried it or some other equally stupid reason. If you have a problem or just want to talk with another teen who understands, then this is the right place for you! Chowing down on fish tacos, munching carpet, dining beneath the bridge, yodeling in the love canyon, lapping the labia — whatever you want to call it, cunnilingus is one of the staples of lesbian sex and hello, any sex involving a vagina! While she once contemplated having a sex change due to the unending pressure to be bit more lady-like, she realised that all she needed was a guy who would sweep her of her feet. Anyway, you might be afraid of judgement because bisexuality or sexual fluidity is often associated with sexual promiscuity. You should only explore your bi-curiosity if you feel curious, if you feel that urge or attraction.
