Sometimes less is so much more and I prefer to be authentic, so I say something along the lines of "I don't think we are compatible" which is a neutral statement.
I have to agree, do not lie or you will be caught out. In the old days I would grin and bare it, no more if a client wont shower and he asks for owo and kissing I tell them why, they are grown men and should take better care of their hygiene. If they discuss other wg's I just say, sorry I do not associate with other girls so do not need to know about them.
It keeps you out of the drama and it sends a clear message that you will not tolerate unhygienic men.
I have stated it on my profile in a humorous way and men take note.
But yesterday I had a guy who sounded like he was hocking a lugy while I was giving him oral and he asked me to kiss him and I just distracted him with other things, i was so scared I was going to end up with flem in my mouth
, but he was a fabulous guy.
But if you have a bad vibe off someone or for whatever other reason just tell them sorry but I do not think this is going to work. IF he leaves in a huff he leaves in a huff unfortunately you will feel a bit bad but it goes with the territory.
