As a fellow "Not in any way, shape or form in the George Clooney catagory" guy, I must tell you that my experiences have completely different from yours, and I suspect that your problem is caused by a combination of "looking for love in all the wrong places" and and some self-doubt about your image which is causing your experiences to be strained and unfulfilling. As to the former, there are many really wonderful ladies who post on this board and whom I am sure would share a great time with you. Hey, I see that Flora is offering herself, and she is both terrific and beautiful (and has a great accent to boot, to say nothing of the most amazing long hair, and a very talented skill set), so you already have one great alternative right there.
As to the later, I can tell you from experience that personality and self-confindence overcomes looks everyday, especially in the Hobby, and unlike looks that is something that you can develop. If you don't wear self-doubt on your sleave, if you engage the lady, and if you try to make the experience fun for her as well, then you will have a GFE. If you are awkward and unsure of yourself, then the lady will feel the tension and and be uncomfortable. Trust me, a good provider wants to please, they take that task seriously, and they could care less about your physical attributes. My suggestion to you is (1) be open with the lady if you are feeling insecure, but do it in a direct way and with a sense of humor, and (2) perhaps pay for a bit of extra time and start by meeting for a drink and conversation, treat it like a date, since ultimately that is what it should be, albeit without the tension and subtexts. Good luck, and keep trying, and you will find your ATF, if not several. And remember, like anything else it requires practice to get it right.
