Thread: Sex with a friend

Have you ever had regular sex with someone who is also your friend in everyday life?
I personally find this idea strangely hot and exciting, but it feels like it is too risky.
I mean, isn't it extremely likely that at least one person will start to get feelings for the other person?
I have heard of people who only meet for sex and nothing else, and I can see this working quite well, but with a full-time friend...?
That sounds really tricky to me.
I believe I have even heard of people who have been fairly intimate with a friend as well, like making out and smiling together, watching a movie in bed while carressing each other etc, and that sounds like it would make everything even trickier.
I actually once got much stronger feelings for a girl I wasn't really in love with simply because we had sex - and I definitely started to get feelings for her when we lay and smiled kindly to each other for a long while afterwards.
So what are your opinions on this?
I can sometimes find myself flirting with girls I know as friends, but I am careful to avoid making it any more "serious" than that, since it feels like one of us is just going to get heartbroken in the end.
I am thinking that if you like each other enough to be friends, then sex and intimate evenings together should certainly make you fall in love very easily.
