ok so I recently lost my virginity to this girl I'm talking to. The first time I went limp after like 20 mins either due to nervousness or the fact that she was riding me so hard. When I'm on top I don't seem to have as much of a problem staying hard. Anyways the first time I didnt cum, went limp and stopped after 20 minutes. The second time she came twice, I didnt go limp, but I still cant cum. Its almost like I've been so used to jerking off that its hard to cum from sex Is it a mental block or nervousness or something? Someone help me here, she thinks its her fault and its killin me.
