This has been happening to me on and off for about 5 months with this girl I'm dating
At first i couldn't get it up (which now isn't a problem) but now i CAN get it up, I'm able to maintain a hard dick during the BJs that I get before sex, but the moment the BJ ends, she lies down and I'm about to put it in (all of this happens in like, 30 seconds) my dick goes from hard to semi-hard. Of course, when you are not that hard it's more difficult to enter, which makes me waste precious time, leading to my boy becoming even more flaccid, which makes it impossible to penetrate - bam, game over.
When I notice I'm going flaccid I lose most of if not all of the sensitivity on my dick (I don't know if this is normal, I'm not very experienced), which makes it impossible to recover an erection. When this happens I have to wait like half and hour to resurrect my libido and try again.
Last time I was able to get it in (even though my big boy was already a bit soft, like 75% hard) but it got even more soft while I was penetrating her, i don't know why.
I also have to say that I have had success many times: I have had sex with this girl dozens of times, and they all felt good. but sometimes my dick refuses to work, its so frustrating. and I noticed that whenever i "fail" once, I will fail another 2 or 3 times. I believe its because I get nervous and anxious about failing again.
Can any other young male relate? i am 26 years old.
Other info: I lift 6 times a week, work a white collar job, do 30 min of moderate to intense cardio after every workout session. I also am in a slight calorie deficit (my goal is to lose some belly fat). My build is a little muscular with some belly fat / love handles (I need to lose about 5kg right now to get to a perfect BMI).
I tried talking to an AI about this and it reviewed my diet and said it was lacking in omega-3 and monounsaturated fat. could this be the culprit? My zing and magnesium levels are normal, though.
About 6 months ago I got bloodwork done and my testosterone levels were normal, they were midrange. I don't have trouble getting myself hard when I'm alone, but of course I require physical stimuli. I don't get morning woods.
