I'm 38, and as with Bones, never had a g/f or close female friend or female friend (though not a virgin, by way of a large sum of money, and a large amount of alcohol!).
I'm just "going with the flow", the thing is the pipe's all bent and twisted!. I have had a fair number of opportunities, but for various reasons nothing happened (one of those reasons being of course SA). So the reason i'm still single is quite complicated.
But, speaking of "flow", i am currently thinking that maybe i might need to do some things that don't go-with-flow (such as make a real effort to try to get a g/f). I'm quite confident that i could get one, but the thing is I don't really want one, and would prefer to stick with my solitary/isolated life, but maybe i "need" one??. Who knows.
