Hey. I had sex for the first time a few days ago. For the first time ejaculation happened in less than half a minute. More accurately maybe 15-20secs. Then the 2nd time and the third time for somewhere between a minute or two. This was in a time period of 7 hours. And I felt like I wasn't getting a full erection during the whole time. Except for the 2nd time. After this we took a little break and when we started again. My penis won't erect. It was just off. I have had a history of masturbating almost daily since I started masturbating but before that day. I dint masturbate for a week or so. And hadn't had an erection for 2 days after this event. I have talked about this with my partner. She had a boyfriend before and has already had sex many times. She also said I dint erect the way I should have. I want to know if there is a problem or I am just stressing this out.
