In the past several years it's been interesting to find my standards regarding what I find acceptable when I'm single versus when I'm in a relationship. When I'm single I have no problem flirting with, playing with (in a kink sense or otherwise), groping, snuggling, or even kissing women that show interest to do so (providing I know they will want to keep it casual, too), whereas if I'm in a committed relationship there is none of that with anyone other than my partner. I still generally draw the line at no-strings sex if I'm single, but I've still crossed that line a few times in my life with "friends" that I knew very well beforehand. Generally speaking, however, I try to keep these kinds of activities to a minimum when I'm single to avoid causing misunderstandings and/or drama, not to mention avoiding picking up colds... and such.

Do other people have similar double standards or have gone through similar transformations?
