Frustrated

My boyfriend just moved up with me after a long distance relationship and with the amount we masturbated together over skype I thought it would be no trouble getting sex.. but he just never seems to be in the mood and I'm becoming so fricken horny and frustrated I don't know what to do.. he swears it has nothing to do with me, he's just not in the mood.. I can't help but be kinda hurt when my every advance is denied.. it's come to the point where I'd love to just masturbate but we live in a studio apartment and I can't really get any privacy.. I just wish he'd try and have sex or even just finger me or something, anything to get me off.. am wrong for being upset by this?
