I typed a whole message, hit submit and gave an error (I'm on GPRS).
Thing is for me, I haven't ever felt straight or gay. I don't lean towards a man or woman either. I've known I'm a messed up individual from an early age. The few relationships I've had in my life were bound to fail, because I always feel like a failure with another person when we are romantically involved.
You seem to be more responsible than other gay man I've heard about LA. Some men live straight lives, with a wife, whole works, but they have experiences with other men, which is a bad thing if you ask me.
If I was straight and married, I wouldn't fool around with a guy (if I was truly gay) and expose my wife to a possible risk of disease or worse death because of disease I gave her.
It's a tough balance at the end of the day. Even I get aroused or have a sexual desire at times. If I act upon it, which I have, that's when I start drowning.
It sucks not having anyone and not wanting someone because you know you are an awful person from your core (no low self esteem here though, just facts)
