Occasionally. Its not just the porn but some guys use too hard and specific a hand movement when masturbating that a vagina just can't imitate. I also have experienced when I've done 'erotic massage with relief' trying to jerk the guy off and it just not happening and then I've suggested i kiss him, or ball tickle or something whilst he does it and noticed they use either a very tight hand movement or a very very specific one that I would never have thought to do for him on my own. I assume then its likely they masturbate an awful lot.

Yeah when this happens it's usually due to Death Grip wanking.

They can re-train their cocks if they are disciplined about not wanking for a while, or forcing themselves to only use a light touch.

I gave myself the female equivalent some years back when I was using a very powerful vibrator at least once a day, sometimes twice. (This was before I entered sex work, I was just a horny fucker!) That vibrator gave up the ghost one day and I could not get the same one anywhere. I had to basically re-train my clitoris to get used to a less powerful vibration.

Talking about specific movements - I tend to see quite a few older men with ED and although they can't get hard they can still cum. But I've been surprised several times when they've got hold of their soft cock and basically just shaken it back and forth, sometimes quite forcefully. One guy I was afraid he was going to rip the fucking thing off!

I've had the same thing with vibrators so I can't use them anymore. They make me numb 

OP, I have noticed a difference in men's performance over the years and you may be right that it's due to porn. I started this job before internet porn became a big thing and, perhaps it's my imagination, but the job was so much easier. Clients were relaxed and easy going about sex. They weren't afraid to cum. I'm finding more and more expect a marathon of non stop fucking or sucking because they either can't or won't finish.
This is just my experience though.

It's also about nerves from previous negative experiences. I see quite a few of them and they seem to open up to me. We spend time chatting and a common theme stems from bad experiences with civvy girls who laugh at size or shape, talk about ex-lovers who rocked their world, laugh and take the piss if the guy cums quickly which of course sometimes they do cos they are really turned on and/or they haven't fucked for ages.

For others it is a lack of experience, often linked with a lack of confidence around females.

I'm finding myself doing more sex therapy with some guys, not that I am complaining haha. It's a win/win they have their confidence built, sometimes they manage to cum in the early days and I get regulars who are happy to go with the flow and not at all demanding.

Now older guys, a lot of porn is watched. A couple of my regs always watch porn before I arrive and have it on in the background when I'm there. Ask them what they have done that week, and it's did a bit of shopping, some maybe been bookies, a couple of pubs mentioned, seen family at the weekend, saw a couple of mates but mainly watched porn and wanked because what else is there to do.

Sometimes I notice with my regulars that the time they last before they cum can vary vastly between bookings especially in my younger aged regulars. One week it can be a 20/30 min session then the next it’s over within a few minutes.

Maybe stress and the like can have an outside influence on things?

I lost my phone guys 😣 got it back now. Love these responses. The general consensus is punters are idiots xx

One thing I HATE is when they are about to come but decide its too early so they squeeze their cocks to stop themselves. Then soft and struggle the rest of the booking and still expect you to get them there. A holes.

Yep, this exactly!
