When I was single I accepted a lot of freebies. I honestly had a great time, and had quite a few 'no strings attached' experiences.
Now though I need to be much more careful because I have an SO. There's just no point in the agro...
The way I look at it, it's bloody hard just trying to keep one woman happy. Why run the risk of having a freebie with a colleague or friend that could easily put demands on you and try to get a real relationship?
"I don't pay them for sex, I pay them to leave", as quoted above, sums this situation up perfectly for me, as I don't want anyone messing around with my real relationship at home.
But... I do keep up low-level flirting with potential FBs and ONSs, just incase I need them one day
, and I still have a small number of 'friends' who I keep in contact with from my single days. I know those girls very well, and I'm fairly confident that they wouldn't mess up my home life... but if it was a random new colleague at work then I'd stay well away
