I'd be asking you are you seeing other women because you want to, or because you think it's the way to make things even. If the latter then you can only be on a soul destroying path. Tit for tat usually doesn't make anyone feel better, only bitter.
It's because I want to, I get on well with my regulars and I like to see 4 or 5 different women a month and I'm finding it difficult staying to one women. Hardcore punters will know (or maybe it's just me) but I've paid for sex for over 15 years, if I feel like having sex, or seen a hot women out shopping or something. It's hard to contain that urge so I have always booked an escort.
It's an impulse thing, I rarely per-arrange days in advance to see an escort.
With her being away, I'm not getting any so I want some, if you know what I mean. Nothing spiteful. I just like sex with many different women. Maybe I have a problem with wanting lots of sex with different women.
But with this situation with her, I just feel, if she doing it, then if I want to as well, then she shouldn't be telling me no I can't, considering this is her chosen job.
