I think you at least gave him a service as best you could.I have had my bed broken by a really big guy and its a pain in the arse but if you are 25 stone plus you must already kind of know that some things are going to be awkward and getting on a massage table is one of them.

Sounds awkward, Ive had some big guys but not that big. I have a problem with not knowing what to say when they start talking about how they hate being fat and eat too much, which they always seem to start talking about.. I have problems with binge eating too and its a constant struggle to stay thin but I dont really want to talk to them about something so personal so I just make sympathetic noises and feel awkward

I have had a couple of very overweight clients and they have both been very aware that because of this sex is very unlikely.

Like someone else mentioned mine both had very small willies too.......even had they wanted sex it would've been impossible, since I'm very slight.

Neither minded that it was more kissing/fondling and oral or handjob.

And the willies tend to have the most awful smell when you roll back their belly.

Sex with overly obese clinets is hard - pardon my words but it's like mounting a horse or something.
I can also be suffocating having someone on top. I've seen bellies bouncing and i think omg! And unless you're very throrough washing in between is folds is hard. 

I think doggy is the best bet, or stick to oral. Unless anyone has an idea of a better position? Perhaps reverse cowgirl? But I don't like to keep trying different positions if it's not really working, it feels awkward and then I feel sorry for them... It must be difficult for some with body issues or low self esteem even to see an escort so I try to give them lots of intimacy and be understanding 

I have one regular who is on the large side. Ever such a sweetheart but some positions don't work and he knows that. I'm quite short though so doggy tends to work since it's kind of at an angle that avoids clashing with his belly. We usually go for reverse cowgirl or with him sitting up and me on top like sort of a lapdance position with his legs open. He can use one hand for support and another to touch me which he quite seems to like. He's not huge down there though so sometimes it can be awkward to find the right angle to get it in and to keep it in so it won't fall out. Better for him to avoid any attempt at thrusting just get him in there and work my hips.

Much of our meets tend to be more oral stuff or him just doing stuff to me.
