hard can be a challenge. But I've discovered something that works for me when junior's acting lazy. I've surprised more than one provider when I request 69 and then ... BOINGGG, hard as a Chinese crossword puzzle. A second or even a third pop will usually fall like a domino.
Do you have any stand by "maneuvers" that works for you when this occurs? FIA? DFK? BLS?  

...I find if we try to get to round #2 too quickly it could be hit or miss.  If we go back to some sensual DFK and close contact that will get me to a certain performance level quicker..sometimes just having her lie next to me, DFK and have her throw her leg over me with my junk under her thigh things will start to 'respond'.

loads any more but I can hold out till the 55minute mark with ease. If my dick is not working it's usually because I am all wound up or nervous. I just go down and eat the muffin for ten or fifteen minutes and always get my wood back.

the pussy, not your Johnson

I try to tell them in advance so they dont rush.

There is something about how reticulated and powerful the hand can be, and that shows the provider's intentionality as well, which is also a turn on

I have a couple of regulars who know me well enough that when junior isn't cooperating her and I will "tag team" junior.  A little bit of handjob from her and jerking off by me and we aternate...plus their dirty talk

For me - P to P massage, DATY, receiving DATO, receiving prostrate play, HJ, BJ, playing with my balls, her playing with herself...  Take your pick, any will make me spring back to life...  Guess I'm just easy...

Any good recommendations for providers who give a good DATO?

A little communication goes a very long way. You cannot possibly shock me or most providers. As for dato if you don't shower when you arrive, it's not an option. So, if you want a good rimming prepare to shower. 😉 Oh and if you want a prostate massage be a good doobie and clean yourself properly. 👅
