I think mostly it is very hard having relationships while escorting. You are right if a lot of guys are ok with you doing this job i do question why are they? I have had plenty of past friends that do this and there boyfriends/husbands knew what they did and they just sponged off them and had no respect for them they encouraged them to work the boyfriends became more lazy as well, i felt very sad that some of the women were putting up with it. I myself could never put up with a man treating me this way but sometimes they do it in a very brainwashing way over time and you do not always see it straight away.
There could be some that have a different experience and find it works with the boyfriend they have and they are both very open minded to this. I suppose it depends what type of man you meet and how you also feel about the sex work too. I think there is some women on here where the arrangement works for them well but yet again depends on the man.
For me but this is only my opinion for myself and how i feel, i would not want to be with a man that was really cool with me doing sex work and happy for me to do it long term i would find that hard. I only do sex work for me.
