I have sex with this girl at my college a couple times already but we're not really dating yet - we don't really see each other all that much. I sometimes look at some of her Facebook pictures and get turned on, usually ending in masturbation. Is this weird or creepy? Should I stop? Remember, this isn't some random girl on Facebook - she is attracted to me and we already hooked up a couple of times. I need opinions from college people or at least my age (21)
