I lost my virginity to a SP about 2 years ago and I do not regret it now. I was 20 at that time and realized, in my life a normal hot and pretty girl will never come and so, there is no point for more waiting. So, I booked a well reviewed independent SP who looks like an angel. And here is what happened in that session- the SP opened the door and let me inside and asked me first- you look young, what is your age? Is it my first time seeing an escort etc? After initial talk and shower, she started to do BBBJ and I lasted about 30 seconds. She was very surprised that I cum very soon. Then she give me some tips on how to last longer. Then we started second round in doggy and I lasted probably about 3-4 minutes. Overall, the SP was really nice and understanding during the session even though I never told her that I am virgin. Personally, I did not enjoy that session very much. But, it is very memorable experience for me, where I came twice within 90 minutes which now is impossible.
Since I did not enjoy my first time (I was pretty sure it was not due to being anxious), later I tried to find the reason. I started to see more SPs. In last 2 years, I saw about 36 SPs and now I know why my first time was not perfect. Apparently, I have type- I like those SPs who are between 5'1'' to 5'3'', weight 95lbs-115lbs, very energetic, really into the session and also like to do role-play/basic kinky stuff.
My advice is, do not take your first time too seriously. There is a big learning curve, you have to keep exploring. By only exploring, you will find what you like and what you do not. Losing virginity is only the first step.
