My girl and I have been trying to get pregnant for 2 years now on and off. Sometimes when we have sex I am hard as a rock and stay hard as a rock until I get off and I always get off in her sometimes when we have sex I'm hard as a rock and then I lose it and she gets discouraged and then it's hard for us to keep going when I do get off it's not much most of the time the only time I get off a lot is when we haven't had sex in a while I'm 31 years old and when I was younger they told me I had low motility I have gotten her pregnant one time at the very beginning of our relationship and she lost it someone please help we want a child of our own so bad we can't see straight but we have a few problems either I can't stay hard or it's not enough sperm or it leaks out or maybe she's just not ovulating we try to track her periods but they are all over the place help please?!??!?!?!?!?
