So I had sex once with one guy (didn't cum because no condom) now I'm with a new guy and we just had sex 3 times, 2 of those times he didn't cum (he just kinda gave up, said because it was too hot but I also think he may have just given up) the time he did cum was pretty quick. Is it normal for a guy not to cum that much? I'm self conscious about it because it feels like I'm doing something wrong because I'm way more inexperienced than him
