I think I see what you're getting at,I've felt inhibited quite a few times in the past with one partner I once had,yet I feel alot stemmed from lack of trust and his own negativity and insecurity.I had excess baggage from a relationship before I met him and I had niavely assumed that discussing my issues would break the ice and make things easier.It didn't.He didn't want to hear my history and was threatened by the idea I'd been with someone else before him...that angered and hurt me.I suppose what I'm trying to say,in my case,sex was one thing I was never shy about,but negative experiences had put a damper on my selfimage and selfesteem...which affected my sexlife at that time very much so.It's the one contradiction in me that I find amusing,I was always sexually aware and curious and when it got down to it,as long as I felt secure with who I was with and trusted him...shy I am not.Crush that trust and all you'd get is ice and a door slammed in your face.I'm not sure if this helps at all.

Kind of odd, but in bed is where I am the least self-conscious.

Sex is one of those VERY rare occurrences with me.
There is really not much to deal with though.
About once a year or so someone manages to find a way past all my defenses.
Says the right things at the right time, and ends up getting me naked.

But like I said, it’s rare. I do blush, and giggle, and do everything that is SOOOOO unmanly when I’m placed in situations like that.
It tends to be a turn off to most ladies. And since I don’t flirt or in anyway actively seek out partners. It’s really not on my mind much.

I guess my only advice is, just wait. If you are shy, then just be shy, eventually someone with take a liking to you. If not, it’s just not meant to be.
