So, I’ve made some progress. Only with the fleshlight, but it’s something. Here’s what I’ve been doing.
I think my problem is, during sex I’m not aroused enough & slightly anxious. I have an erection, but the spark isn’t there, & my penis feels numb & I can’t let go. I’ve got a feeling that subconsciously I don’t want to cum & feel humiliated for going to quickly, so I end up not being able to cum at all.
What I’ve been doing is masturbating (very lightly, since I too used to use a tight death grip & have suffered from it) & getting to the point of being very close to cumming. I then enter my penis into the fleshlight. The first few times it was too much & I came right away.
Then, I realised I could stop myself by doing a few slow slow strokes in the fleshlight….& to my surprise that great, sensitive, “feels like I can make myself cum any moment” sensitivity remained…like how it feels when I masturbate….like how I imagine sex is supposed to be, because it was so good.
At this point I’ve been able to keep that sensitivity for about 2-3 minutes, then I either cum or my dick goes numb again. But at first it was only a few strokes. then 20 seconds, then a minute etc etc so it’s getting better. Problem is I always have to masturbate to the point of nearly cumming first to get my dick properly aroused..if I just have an erection & enter I’m never gonna cum, but atleast it’s improving.
