Someone else can give you the "are you sure you want to lose your virginity to an escort" talk.
Whilst you say sky is the limit for your budget, I'd stick with no more than £150/h for a first meet.

External Link/Members OnlyKendra has received some favourable reviews recently, including myself. The services that she provides are what I find "standard" for a GFE meet, OWO, DFK, protected sex. Being your first punt and with the weight of your virginity, I'd recommend Kendra on the basis that she generally isn't too strict with times and she warms you up to the meet with some chat, before and after the fun stuff.

External Link/Members OnlyWhilst she provides a plethora of services, GFE is one of them and is what I'd recommend you stick to for a first meet with any escort til you find out what your kinks are ect. She can assume any role you desire for a meet, the sweet girlfriend, the tease, the kinky. Again, probably stick to simple for a first meet and explore if you end up hooked to punting.

External Link/Members OnlyTours the country and is making a stop in Glasgow for a few days in January. A beautiful girl and knows her way around the anatomy. Very sensual and accommodating in my own experience though YMMV.
I recommend sticking with British blood for a first meet, the above are all well rated and Scottish to boot, prices from £130-150ph from the top. Reviews of them should show below my post so you can read through them yourself and make up your mind. It is up to yourself how you go about it, but discuss in emails what you're after with whoever you decide, try to keep it concise and to the point as possible to avoid looking like a timewaster. Generally speaking, you shouldn't mention it's your first time punting or you're losing your virginity ect as it's usually a sign that they can waste your time and so on. The above three though from what I've heard should be receptive to this though and possibly allay your concerns. Up to you of course, but it's things to consider if you're intent on this course.
