Boat, here's an article you might enjoy:
http://www.theguardian.com/society/2015/apr/01/future-of-loneliness-internet-isolationI never could have adapted to younger generations' assumptions that "dating" equals "having sex with" (in an astonishingly short amount of time). I read somewhere that by second date is just routine. DANG.
In my wild 20s, I could make those same choices (and did and enjoyed it) but it was because I had no sense of the future, of what I really wanted yet. Which later became pair bonding, shared lives, domesticity.
Now that I do know (or want this dream again)...it's going to take a patient man who wouldn't dream of pushing me about it. My internal clock says, well, maybe if we've gotten to know each other over about six months. Sure, the right person and chemistry could speed that up (kind of hope it does). But in general, and I know this is way different than for most people younger...I just don't want to sleep with anyone casually again.
My hormones kick in with intimacy and I bond like a baby duck. Too painful to be easy come, easy go...and that's because I've been lonely too.
If I were allowed only one taste of chocolate, ever, and was told it was the food equivalent of heroin, but I could only eat it once or not at all...these days, I think I'd pass. Try to fall for a flavor that IS available.
My thoughts about your online attempts to ease your loneliness are the same as ever.
Go 3-D.
Start with groups.
Art class?
(You can make paintings of sexters.)

love,
