We all have different reasons for being on this fantasy site and I have been in the 'hobby' for a long time.
My sexual prime was when HIV or AIDS was happening but no one knew it. I was lucking enough to go to college and alcohol really made parties happen. I had so much 'unprotected sex' that I count myself as lucky. Note: if your son is an engineer but takes classes in fine arts he is really smart kid. Not...many horny woman engineers. That was/is sexist but I don't care if I am judged.
BUT...my reason for joining the hobby was simple...as a GF I got great bbjc's but literally they stopped as soon as the ring went on. So after years, I made a decision to 'join his hobby' but I talked to a doctor first and I have continued talking to my doctor's. I didn't want to hurt my wife but I really enjoy a good BBBJ with CIM.
The risk of a man contracting a disease from a BBBJ is very, very low. Sex without condom is just stupid. In all my years, I made the mistake once and it was because the provider was crazy hot and I stopped thinking. I had myself immediately check, re-checked and then resumed relations with my wife.
This risk of a woman contracting a disease from a BBBJ is pretty low but if the client has syphilis then you could be at risk. (read below for more on this) Note: I have asked this question of a female doctor, it was awkward, and she demanded that I take a long list of tests but a female doctor gave me the facts of the risk to woman. She was trying to shame me from my behavior but even before HIPPA patient doctor confidentiality was a tenant of healthcare. I will admit I never saw that doctor again but I did ask and I created my rules from this information
NOTE: I am not a doctor, I don't play a doctor on TV and remember this is a fantasy site.
A small sidebar:
My ATF, she is retired, was a woman from Sacramento, CA. He name was SubmissiveSlut. Her rules were very simple. Do with me what you want, as many times as you want but no anal, no unprotected cunnilingus and you cum as man times as you like. She always had female condoms. She was submissive but she stated her rules very clearly. I mention her because she openly talked to her gynecologist about her job and oddly she disagreed about syphilis. She was told that that saliva and stomach acids take care of the risk. NOTE: I don't think she was a doctor either.
Here are my rules
I never perform cunnilingus . Don't get me wrong, I love doing it but not when I hear all the reviews of making a woman cum 4-243 times in a 30min-12hr date and DATY made it all happen. I have previously made my position well known about 'fake reviews' so I won't start that rant. This is a fantasy site so I take things with a grain of salt and stories make for great reading.
There is no doubt that good foreplay makes for better sex and if a female condom is offered...I will consider cunnilingus but again I am very selective.
I never have unprotect sex. I have been known to like Anal but I am very cautious of who I decide to do that with and I NEVER do that without LOTS of lube. The lube is all about making sure no blood vessels break. Note: I had this explained to me by my doctor and yes even my wife.
Herpes...well that odds are that everyone has it but to different degrees.
Just a funny story...STD's are a HUGE problem in retirement homes and communities. If your guy that ages well you are going to get laid more than you did when you were in your 20's. This is a statistical fact!!!
Be safe and be respectful
