Not satisfied

I’ve been with my boyfriend for six months, he has came countless times. I constantly beg him for sex and most of the time he’s not in the mood or doesn’t want to, we only see each other twice a week, so we fuck a couple of times when I see him. I have never came or orgasmed with him before, I never moan..But we have no privacy so he says we don’t have time to take things slow..I’m almost never wet when he does decide to have sex with me, but he just spits on his hand and keeps going..I’m beginning to not enjoy it, but I still want it all the time..
