I've known I'm into girls (and boys) all of my life. I was always the one initiating the games as a little kid. I fooled around with girls until middle school, and then everybody sort of started defining their boundaries, and being gay was not acceptable (especially in a Catholic school) so I and even the girls I messed around with chalked it all up to childhood experimentation and closed that off.
Went off to college and started dating guys, and that hasn't stopped since. I have been married and divorced as well (a long sad story). When my marriage fell through, it was a lot like having a carefully erected house of cards collapse on top of me. It had never been as stable as I'd thought, but I'd certainly spent a lot of time and concentration trying to build it. I sputtered my way out and decided to stop defining myself by the structures around me (religion, marriage) and to go back, if you will, and find out who I am.
At this point, I'm not sure what's going to happen. I am with a wonderful, monogamous man, and I've never been non-monogamous. I have a couple of female friends who have my attention, and certainly I find a lot of beautiful souls here on lj... don't know if I am going to end up kissing, making out, having sex, or having an ongoing fling. I don't know if I will explore this until I get married, and then be satisfied, or if this will be an active part of my life for the rest of my days. I do know that, now that he and I have discussed it, I am pretty damn excited to find out.
