I have experienced a couple like that lately but thankfully they were all too drunk or high to require intercourse as, lets say things weren't exactly working for them
Not sure what i would say to a guy sober though! Sorry sweetheart but you're simply too small! Probably not the best thing to say.. ![Huh? ???](https://saafe.info/main/Smileys/classic/huh.gif)
It's always a bit of a tricky one but you must never be afraid to be honest and frank with a client, especially if it's a sexual health issue at stake! The old "Oh, but I
much prefer to use my hands/mouth, it's so sexy and really turns me on!" chestnut works best in this situation - that way, you only have to bring up his willy size if he rudely tries to insist that you risk your health by having sex with him despite the condom slipping off, and in that situation, he'd bloody well deserve a bit of a wake-up call.
We can't all do everything in the bedroom, after all. I could go around being rude to people because I felt bad about not being able to deepthroat or whatever, but that would just be silly and I don't even feel bad.

I'm pretty sure it's possible for a smart and sensible grown-up man to accept his own limitations in the bedroom, too.
