Doing this job isn't an easy thing to do, you need to remember you are being paid though this is a job and sometimes doing work there are things you don't enjoy it's not all having sex with men you find attractive (though sometimes there are some nice surprises!) and you have to be able to get into work mode where doing the booking takes priority over your own feelings about how they look, I've had sex with lots of guys I wouldn't ever consider dating in real life but they pay well and they are just normal nice people so it's easy really, the ones you have to worry about are the idiots and time wasters you encounter I've had one scary encounter but for the most part I've avoided anything too bad, guys who are fat or not good looking are the least of my problems.

If you're not a people person, can't enjoy the company of different kinds of people and be able to push through spending time with people you aren't attracted to while acting like you are enjoying yourself then it's probably not something you should do, it can be mentally draining even if you can handle it and have enthusiasm for what you do. Remember you are being paid to provide a fantasy to your client it's not really supposed to revolve around your own tastes.

It is weird when you first start out. I remember it well. Does take a while to get used to having sex with strangers who you wouldn't look twice at in the street. We're not programmed to screw guys we're not attracted to are we.

I still have flinching sessions afterwards sometimes, especially if I see a guy in the street when I'm not working, & I think he may call me when I'm back at work.

The creepy ones, I find, will generally let something slip before they arrive. If they don't & do something offensive when they arrive then just tell them to leave. With the smelly, if they turn up & refuse to wash then ask them to leave. Obese guys will sometimes say on the phone "I'm a larger guy". I find the overweight guys are really respectful & quite shy types who are easily pleased. Don't recall having a bad one.The smelly ones I'll avoid, just wont see again. Sometimes they come out of the shower & still smell. Pheromones or something. Get some Badger balm for under your nose. 

You can put whatever you like on your adverts. I've read some women wanting a photo before they'll see someone. (Hopefully they'll not send not send a dick pic  )

I put watsapp on my work phone to see what guys look like.

Thanks everyone you've all been so helpful,  I couldn't have asked for more genuine honest answers!
