Therapeutic genital massage?

[Meow]

i have a kind of...awkward question. I had this guy on my table tonight and he wanted his butt massaged for the whole hour. which i thought was a little weird but he proceeded to tell me about an injury he had 7 years ago where he fell and hit his crotch. he told me that he had been working with a lady for 3 years but she married and moved away. i didnt think it would be so bad. he told me that she would work right in the butt crack and up to the balls and even work on the balls themselves! he admitted he will get a boner when she does this but insisted that he was not looking for a sexual massage. so i thought "ok well, i'll give it a shot". he made the appointment tonight before i had any time to look up any techniques for this particular situation.....and now i cant seem to find anything on this.... and i did work all the areas he told me that she did. but it got kinda weird when he kept asking me to put more pressure on the butt hole and when i worked around the balls he kept asking me to go up his penis :/ which was really creeping me out. he said if it made me uncomfortable it was alright if i didnt. so i told him i would rather not. but he kept trying to get me to work on his penis!
.he texted me and asked me if i enjoyed massaging him. i am very leery now about his whole situation but he wants to meet 3 times a week and give me $60 instead of $40 (he says he paid this other girl 60)

I dont want to just turn him away if he has something that he really needs help with,not to mention that i could use that money! but i have the feeling that he just tricked me to get off.

i feel really stupid and i am not sure what i should do....
