I can't relate but I'm posting cause maybe somehow you could take something away from my response.

I'm 22 and I Rarely get attached by having sex. I tend to keep things in perspective - I'm horny, he's hard, and I feel like putting it use >.> For me it's purely physical gratification... I've had one nighters and I use the guy purely for sex because I'm in the mood and I know he won't say no >.>

<.< That sounds so bad. The way I see it, I don't spend a second thought for a man that I know I can use and I know he'll use me - the sefishness is mutual so being aware of it makes me not trust him, and when you don't trust someone you dont get attached. If someone is trustworthy and Cares about you, Really cares about you, it makes the sex much more meaningful because you know that he won't abuse that privelege.

If this is BDSM related sex than it becomes much more difficult to not get attached, this has been my experience. For me to play with someone, I have to Know them, trust them, and be attracted - generally if I have a session with someone I tend to get much more involved emotionally. So now that I don't have my bdsm play partners I am Much much more careful with who I actually play with. You have to know the other person's intentions, your own feelings for the person, and whether or not it's purely sexual or if it can become something more than that. If you realize that feelings aren't mutual, than it is usually better to stop playing and have some self control as to not allow yourself to be intimate with that person because having strong emotional connections can be reinforced through intimacy.
