As of late we have both said that when we r near each other we feel a little spark and we have both imagined or dreamt having sex with each other. We also both said we can't get each other out of our minds. I don't know if I wanna start a relationship with him tho cause he always talks to me about his crushes and he has dated my best girlfriend. The problem is when we both have a high sex drive but when we r near each other it is multiplied by ten. We have never done anything to each other besides him feeling up my leg. What should I do?
