Hey everyone, I'm a 17 years old male and going to become 18 in a few months.
this has been happening for quite a while and I'm afraid there's something seriously wrong.
Anyways, sometimes when I masturbate and I reach that point where my whole body is experiencing that great feeling, just before cumming, I feel that something is stuck in my penis and that my cum has been stopped at that point with a feeling or getting pinched at the same point, then everything goes normally AS IF I actually came but there's ABSOLUTELY nothing, although I check my underwear after 5-10 mins or even more, I find nothing most of the times. In rare cases I see some cum.
On the other hand, 60% of the times I masturbate or something close to that I actually cum like a normal human being, no pinching, no feeling of something stuck, nothing goes wrong.
PS: I know it might seem ridiculous but 99% of the times I fail at cumming is when I'm masturbating while I'm lying on my side, but that doesn't explain the pinch and things going wrong, does it?
