I would have the option to get a permanent F#ckbuddy but..

He only wants to blow without a Condom.. So i have to ask this Question.. how high are the chances that i could get anything.. i do know he had multiple different Dates over a long time span and given he all blew them without a Condom.. im just afraid i could catch something.. if i could even catch something at all. Are there any risks? After i had some Dates i checked up at the Doctor and he seriously warned me that i shouldnt continue doing it without a Condom.
