Okay ... thanks ... I'm just wanting more insight from other escorts so I can get a better idea of what offer ... I'm obviously going to offer sex but what other services around sex do other escorts offer ?
As others have said, it really is up to you what you offer - don't offer anything you're not happy about, or you'll end up making yourself miserable.
If you're going to offer GFE then most clients will expect that to include kissing, OWO (oral without condom), receiving oral, and vaginal sex with condom.
Have you been on Adultwork and looked at escort profiles? You will see a list of "Likes" which are the services that escort offers. That may give you some ideas about what you do or don't want to provide.
I personally have a two-tier service, the basic GFE which includes all the above, then I do a VIP services which includes full body rub, shared shower, rimming both ways, prostate massage and strap on. I also offer roleplays e.g. slutty teacher, sexy secretary, strict office manager, etc.
