I am 23 and I lost my virginity about 4 months ago. I had gotten blowjobs before, but this was the first time I've actually had sex. It was with an escort. To my surprise, I had trouble staying hard. Initially, I got hard and put it inside her and we fucked for a bit missionary position. But then I pulled out and we took a break so I wouldn't finish and I got soft. We tried to do it doggy style, but I couldn't get hard enough to go inside her. She sucked me to get me hard and it would get me kind of hard, but it would not stay hard long enough for me to get inside her. Eventually we tried missionary again and I managed to get hard and put it inside her and I came after some fucking. The second time I came back to this same girl another time and and I could not manage to get hard long enough to put it inside her at all! I was hard at first and she sucked me but then we when she went to put on the condom, I got soft and could not get hard again without her sucking it. But then when she would stop sucking it I would go soft again. The third time I went to another girl and managed to get hard and put it inside her, but this time I had a different problem, I came right as I went in. I had not masturbated the night before this time and this is usually what happens when I don't masturbate for a while. The fourth time I went to the first girl and I managed to get hard enough to put it inside her missionary position but then when I pulled out and took a break, I had trouble getting hard again. I ended up having her lay down and grinding my dick between her legs and I managed to get hard and do it doggy style but I came pretty quickly. Idk if I have ED or anything because sometimes when I get turned on I would get really hard and have trouble getting it down. But often times even when I am looking at porn and masturbating, I have to start stroking it a bit to get it hard. So I am pretty embarrassed. I often hear online talk from women about how "young guys have stiffer erections" and "they can go all night" but this is not the case with me. Am I normal for my age or are my sexual abilities more like those of an "older guy"? Or is there something else going on? I would really like some feedback on this.
