I've read all your posts iimmscared and i don't see homosexuality. Most gay men are always gay, never having a desire for women. Some men "discover" that they are bi-sexual but do not lose their desire for women but realize they also desire other men. You have said that you have been with other women and enjoyed it.

From what you are saying this seems to have occurred with your current girlfriend. Until then you were strictly hetro. Perhaps there is something about her that has triggered some repressed memory or emotion in you that is trying to come to the fore. Such a sudden shift in how you perceive female anatomy does not equate to a change in sexual preference.

I would suggest talking to a therapist, one specializing in sex therapy.

Good luck, and don't let it bother you too much. Everyone has a little confussion about sex from time to time.
