I'm 21 and have always considered myself straight.

However, last week I went to a colleague's leaving party in London, where I work. Everybody had quite a lot to drink and I ended up sharing a bed with a very attractive older woman. Much to my surprise, she helped me to orgasm several times. Does this mean I am bisexual? And if so, could I get some medical treatment for it?

I would say we all have some element of bisexuality in our natures. There's no medical treatment to stop a person from being bisexual.

However, you could do with a bit of counselling to help you sort out your ideas. Call the Brook Advisory Centres for Young People on 08000 185023.
