If you have, you are most certainly not the first, and definitely won't be the last. Saw a recent post in the newbies board and someone left quite a good comment, so check it out if you have a chance.
But I don't think it is not uncommon for a hobbyist to have crush on a provider. First of all, the ladies are beautiful and more often than not, we chose to meet them because they are our ideal type (body, look, hair color, eyes color, etc). We already like them in one way or another before the session begins. Then, there is the GFE - and the Doc covered it pretty well. Our feeling is not a light switch, we could train it to be, but it is not easy. We are not robot. Finally, if the lady has an amazing personality, it would be impossible to not like, have a crush or maybe even fall in love with them. I don't know about fallen deeply for a lady, but I have my fair share of crushes on companions.
Do I think this is wrong or I'm crazy? No. I'm not looking for a cold, emotionless transaction. I'm looking to connect with a lovely lady that I know I'd enjoy spending time with. Sometime it takes me a day or two to gather myself, but at the end, it is still a p4p. Instead of avoiding to admit it, just accept the fact that we are all human and it is ok to have a feeling for someone. Admit that you shared an exceptional experience with a lady, then move on.
