I have a client who admitted to taking it after I added a note on my website that I don't consent to it, as I don't offer PSE and can't fuck for hours on end (or words to the effect) and still be able to walk/work. The worst part is, he books me for travel (48hrs+) so it's not just a one time ordeal, and every time it takes forever, he still loses his erection quite easily like if we don't change position quickly enough, he moans about condoms being too tight when I've used the same ones on bigger men with no issue, and he gets physically too tired himself before he climaxes more often that not too. I don't know if he's just spent too much time with his hand also, but even after what feels like hours of PIV he still usually cums from giving himself a HJ while I play with his nipples. It makes me feel a bit weird, like he's not enjoying the sex enough and that I'm enduring it for no reason. But he keeps rebooking and spending a fortune, which is the only thing I can reassure myself about  It seems like its far more frustrating this way, but he was conscious of not being 'in his twenties' anymore and wanting to 'make the most' of having me around. He's only in his 40s, fwiw

I did have a regular before who struggled badly to maintain an erection . He told me he took viagra before the visit but it  clearly helped him  during sex. He didnt manage longer than 10mins though, was exhausted physically poor guy , just asked for hand relief to completion in the end .

It does seem to work on some men, but makes little difference to how quickly they cum. So you get these that manage the erection okay when they otherwise wouldn't, but nothing more than that.

I had one who had taken it before he arrived but it didn’t kick in till near the end of our half hour booking, he asked to extend but he had been so unbearable pushing for personal information throughout that I declined and sent him down the hotel corridor with his hard on.

This made me laugh a lot ha ha ha. Brilliant.
