For instance, I know I don't have a big cock. Some girls have a pussy like a glovebox. The wheels on the bus go round and round.
I like believable lies/dirty talk. Its all about phrasing and placement of the words. If she says "I love your big cock" I know she is lying and its a turn off. I like to have my cock complemented just as much as the next guy. So the girl has to get a bit more creative. I prefer "you have a nice cock". To which I reply "tell me what you like about my cock". Then she replies "I like how it feels in my mouth, I like how hard it gets, I love stroking it and sucking it, I want to see your cock cum" Then I say "I love your tight little ass, I love watching you go up and down on my cock while looking up at me." Etc.
Lies 101: I don't have to feel like the star quarterback but i still wanna be in the game. The best one I've heard so far when asking about my dick. She told me I have lot of guys beat and its a nice looking cock. To me thats right in the middle of the road between lies and could be true.
On another note,the more rushed I feel the less likely I am to cum. I tell providers up front it takes me a while to cum. So when the chick starts pumping fast and telling me she wants me to cum 10mins into it I feel rushed and loose my wood. My suggestion to providers is if your not into it that day for whatever reason, take the day off. A bad review for poor service will cost you more in the long run then taking a day off. Don't get me wrong you don't have to be dripping wet or moaning all the time. Just don't double book and make if seem like work.
