So I have been having vivid sexual fantasies about my best friend, she is a beautiful person inside and out, as my relationship become increasingly tense with my boyfirend, I sort advise and support fom my best girlfriend. She is a great listener and very affectionate.

Lately I have dreams of us having sex and playing with each other, we did kiss once in real life, when drunk, and it is with that thought that most of my fantasies begin. They are explict and detailed.

I told my boyfriend the other day and he thinks it is hot and the idea of the two of us being naughty is exciting to him. He suggested I'm bi-sexual, but there has only been 2 girls in my 30 plus years on the planet that I have thought of this way.

Should I tell her? Her friendship is the world to me and I don't want to damage it, likewise I don't want to behave differently around her... plus if she felt the same that would be very good, I think!

I would say that if he is not bi, and also if she is, but not interested you in that way, it is most likely going to ruin your friendship.

What would happen, lets say, if some man you work with, told you that he was having those types of thoughts about you, how could you handle working with them, if he looked at you would you think they were having sexual thoughts?

I would say be careful... every relationship does not have to be converted into a sexual relationship. This is the sort of situation which can potentially lead to losing a best friend for one reason or another. Having a real good best friend is an extremely valuable part of one's life, not to be treated cavalierly.

If you feel okay with it, tell her you think YOU are bi. See her reaction. Then if there is no "oh really" wink wink from her I'd say leave her well alone. Leave it as fantasy.
