I've had this issue, since my early 20's i'm now 53yo, so no chance of fixing it, and i've tried most things. I've since shrinks etc over the years, but most have put it down to my inability to stem my excitement in the moment. I was a virgin until I was 23yo, and until that day had never felt, smelt, tasted or fucked a pussy but was masturbating up to 5 times a day just thinking about it. So from then on they think i've been locked into this 'adolescent' desire for sex and pussy that I never grew out of. As soon as I enter a pussy, I have the same overwhelming feeling I had the day I first fucked a pussy and just ejaculate almost immediately. My ex-fiance used to see how quick she could make me cum, so it got faster and faster, but I haven't been able to slow it down at all. A 2 minute stop and start fuck would be the longest i've lasted in 15 years.
BTW at the moment my wife only fucks a friend of ours (for the last 4 years), who's mid 50's and white, but its probably 50/50 whether they use condoms or not. Usually depends on the mood, if they're ******* and whether she ovulating or not.
