He can’t make me cum

Danesha • I can’t ever keep track of my period, so i just go with the flow😄

Me and my boyfriend have been together for almost a year now (on and off). We are also In a long distance relationship, he goes to college three hours away from me, and I never get to see him. We go months without seeing each other.so when we do see each other we usually are mainly thinking about having sex. But I never am able to finish. He really tries but it just never happens, and he finishes kind of early every time. What do I do? Because he cums every time but I’m just never able to.
