there is lavalife
www.lavalife.com
I tried for a few times. they have intimate section.
girls in that section seem to look for some sex however I found that they are looking for specific guys, like really good looking, nice muscles, etc.. everyone there has specific thing they are looking for.
so if you can meet some of those criteria of some girls, you could get some actions.
I didn't get much, except one time (about 4 years ago), this young girl (19) wanted to do it so we were set but then she didn't want to use condom ??? so I said no (for STD issues) then she said no condom greek. I said no, I don't like greek at all.
good luck at dating sites.
