Is it normal to think about affection 24/7?

I have an orgasm almost everyday all day. I'm always daydreaming about amazing foreplay or having sex with the last guy I hooked up with. Sometimes I just go back to exactly what happened with me and him while hooking up and begin to have an orgasm. It can be during watching tv, "talking" to a friend", in the theatres, etc. Its funny cause the most intense orgasm I have is in public. I just love affection and as I get closer to losing my virginity (oh yeah I'm still a virgin haha :P), I think more and more about affection and having an orgasm. I try to imagine myself hooking up with a guy other than the recent one but it doesnt feel the same. It has to be the last one in order to feel that intensity. I somtimes think after an orgasm, "this can't be good" especially during lecture or family reunions, its hilarious but I just can't stop thinking about sex! Its so natural in me to want it, I love it! but then don't? but I still love it more lol. I think its something not to be ashamed of as long as you have control. Its not like Im going out trying to hook up but when it comes to me and if I feel right about it depending on who, where, when, etc, then Ill go for it. I dont care if he "thinks hes using me" because Im using him as well, we're both there for affection and to get it over with. People are just close-minded about the guy being the player when girls get horny too and they look for affection too not just a bf! The point is, I just wonder sometimes, I need to have control over these 24/7 orgasms.
