Could I live without it, well yes I could as im currently living without any regular sex (have done for years in fact, being that i'm not into one night stands, and I haven't had a proper relationship for years now - not that I wouldn't like one

)
Do I like living without it, no. When im having sex I like a lot of it, but that's just me, I can still live without it, but its not something I would have chosen for myself, although maybe I inadvertently did when I chose not to sleep with random people on a regular basis.
I would like a more regular sex life though, heck any kind of sex life would be nice right now!
I have a medical condition which can sometimes mean sex is painful, when I first got it I was in a long term relationship, he was patient for quite a few months, but then he went off with someone else. Not sure if that was entirely down to the fact I couldn't have sex with him, but am sure it had something to do with it.
I cant see myself ever being in a position though where I led there "for his sake" because thats just not what sex is about for me, its about two people enjoying eachother, and the fun and fulfilment that comes from having sex. I also can't see myself ever having a one night stand because there has to be something more there for me to want to sleep with them.
