Premature ejaculation issue at 48, what gives?

I’m now 48 years old, been married 10 years and I have developed a premature ejaculation issue for the first time I’m my life. I’m trying to determine what may have contributed to this, and how best to resolve it. I think it may be a combination of things; here’s what I’m thinking.

Some background 

I had a normal sex life from my late teens through my 30’s. Some times I would pop quick with a new girl, but I was all really normal. 

I have always been one one of those guys that gets a boner quickly,   And most of the time could maintain erection immediately after climax.

35-40yrs While dating and early marriage my wife was on the pill, until we decided to have kids.  When we were not trying to conceive, I used a condom.  I lasted as long as I liked, longer with condoms. Frequent sex.

43yrs I started PE mostly for length work, my girth good and addition gains came easily.  Still struggle a bitIrish length gains, but that another story. I have 2 kids by this time and sex infrequently. 

46yrs after our 3rd child I continued using condoms, and I could go all night, and sometime had trouble climaxing with the condom on. Sex infrequently. 

47yrs got a vasectomy, we really did not like using condoms.

48yrs we’re still having sex infrequently (hard to find time and energy with 3 kids). Of course after the vasectomy I ride bareback, and now that I am, I come really fast, in stay 3-7min.   What’s going on!

What interesting is that during intercourse the normal slow build up to climax is just not there.  It seems like I just get started, and then I’m at the point of no return, no build up, directly to the pop. My wife’s Vag is nice, but it’s not magic. 

I have noticed that If I can get past,the first 3 -7 minutes, them I last as long as I like.  But right now that’s the problem, I’m just popping too soon.

Another interesting fact, when I’m getting a BJ (also not very often), I last a long time maybe 15-30, and need to work at it to achieve orgasm.  I like to bust a nut in about 15min, or my wife get tired, my girth is 5.75”.   The build up to climax seems normal, slowly building, more intense, etc.  

I jerk off like once a week, usually with porn, I don’t rush it.

Potential things that might contribute to my issue

- Riding bareback after some condom use
- Infrequent sex
- Penis Enlargement
- Age
- Weak PC muscle

I don’t think it something in my head, I think a cause may have something to do with penis sensitivity,  as I know if I were wearing a condom I could go as long as I like.

At this point I have not done much to resolve this, as I’m not sure of the best course of action.  I really want to get back to going as hard and long as I like.

I look forward to suggestions from this great community.

Hmmm… I cannot offer advice, just experience. I am 35 years old. I masturbate once per week on average and I ejaculate with my GF 5 times a week, some way or another. (Use your imagination. :) )

I can also last all night with a condom.
I usually take 10-15 minutes to cum from a blowjob.
I usually last the same or more during sex, but I change rhythm or positions when I feel my PC muscle tighten.
If I don’t, I can cum in as little as 3 minutes.

I had a frenum piercing a few years ago and it makes me last longer, probably due to the scar tissue there. The above is with it removed. (Her teeth catch it). If I have it in, and go bareback, I can go 20 minutes or more.

As a side note, on nights that I do my routine, I last Waaaayyyy longer during intercourse, probably from de-sensitization or fatigue.

I should add that if I put some lube inside the condom before I put it on, it cuts down the time it takes me to cum dramatically, and is a whole lot easier on my Girlfriend.

Hum, that’s a tough one. I find that if I don’t empty my bladder before sex I don’t last long. If I do I can go however long I want to.

I’m not sure why, but I just make an effort to take a leak before.

Wish I could help more.

Well, sensitivity, is in the head, isn’t it? But I’m a bit curious, after the vasectomy, do you worry less about cumming? I think I would. Worry free sex with a nice and new sensation (new because it’s bareback + worryfree), could that do it?

Not really experienced in this world of vasectomy and wives and I hope you find the solution you’re seeking.
