my first time was also with a massuer/escort and was with https://rentmen.eu/Harris_Asianstud. I agree with Dirks above where the pressure of sex is not there. The erotic massage just naturally leads to massage/play and then kissing, oral and anal. It was so comfortable that way and have been hiring ever since I have not been with Evaldo but based on his reviews seems like you could not go wrong. However, majority of professional escorts would happily just start of with massage and would take it slow and your comfort would be their number 1 priority. Within London, I would recommend the following for versatility:

https://rent.men/GabrielCross (as above)

Hope you find someone and I am sure you will really enjoy it!
