I can't no more!!

I've been so OD stressed lately because of all of the AP classes I'm taking and trying to deal with my mom's constant blaming me for random things when we all know it's not me at all and handling a relationship... Is sex a good stress reliever? I've been feeling horny for a while and my boyfriend and I haven't had the time but he's coming over later and I just really wanna take my mind of shit so, does it really help?
