for young women to get crushes and be attracted to other women. It doesn't mean you have to a complete lesbian, it doesn't mean you have to follow up on it.
My advice is if you have the right opportunity iwth the right woman, maybe even as a threesome wtih your boyfriend who will surely appreciate it, then go for it. Otherwise, just enjoy the feelings and celebration of female-ness. :)
I do tend to regret what I don't do more than what I do do, but that's just me and I've done it ALL just about. ;)
