Am I a sex addict?????

So me and my boyfriend have been seeing eachother for a year now and before that we've tried making things work and now its finally starting to. But i have always been the one more sexually active than him... Im the only one hes ever been with.. Anywho... Im always initiating sex i dont mind it but alot of time he turns me down which is fine hes not doing it to be a jerk he just isnt always in the mood... But i am.. Like i always want to have sex with him. I can go without it but i always try to get some. Sometimes he gets upset about it and it makes me wonder if i have a problem or if im a sex addict?? Idk what to do or who to talk to about this...
