I don't want a relationship with them as in marriage or lovers that would be eww and weird to me. Its just if i'm having sex with them casual or not, I don't want to feel used. It seems to me that they are making plans about there next sexual encounter with me without involving me or making sure that I actually want it. But thats the confusing part too is that certain parts of me do want it anyway they can get it but other parts are different and only want sex after a commitment. We have all been friends for years. I just want it to go back to normal without the pressure of sex.
