A few thoughts here:
When you say "escort I found online," I presume that you have actually met this person in the flesh. Falling for pictures and text on a computer screen is a ticket to disaster.
Also, be sure that the escort's feelings for you are reciprocated and genuine. Escorts are in the business of making their clients happy, and will lavish compliments about one's body, personality, sex technique, choice of cologne, etc. This is theatre, not reality. It's pleasant in the moment, but it's not real.
Finally, one cannot expect exclusivity. If you "fall for" the guy and start dating him, know that he's still going to be having sex with other people. If that triggers jealousy on your part, this is a situation to be avoided.
On a personal note, a couple of years ago I started dating a guy I met at the gym. I soon found out that he moonlighted with an escort agency that provided companionship for women. Most of his appointments were as arm candy for dinner, theatre, etc., but some of the time it would include sex. He was indeed quite gay, and very much a bottom, but in his own words, "I have to pay the rent." I suspect that I would have been jealous had his clients been men...but instead I only asked that he wash up thoroughly after his appointments.
