I’m not going to go into specific details, because I believe it is against the rules of the forum and it was a while ago, but I have been unfortunate in the past and caught a dose from an SP. Never from civies. Before anyone asks, it definitely was an SP and I know who it was. Given I’d not had any sexual contact with anyone else for a while, it could only have been this SP. She’s a well reviewed SP as well, not some dodgy skank.
I can't remember who it was but there was a girl on AW who put on her profile that she contracted syphilis, that she had contacted everyone she had seen, and was not working for the duration you're not supposed to. Hat off to her for being honest and open about it, some wouldn't.
I've been through the whole "do it bareback, panic for 3 months that I've got HIV" saga when I was younger, it isn't worth the stress or the risk.
And then when you get married, you really can't be doing that stuff. 1 of 3 things could happen..
1) you get a bird knocked up and she keeps the baby.. that will be an interesting conversation with your wife...
2) you catch an STI and then your wife finally wants to have some sex and you unwittingly pass it on to her, except you can't ask her to get checked, because why would you, you've been her only sexual partner for 10 years, can't see a way out of that unless you spike her drink with antibiotics which probably wouldn't work anyway
3) you get HIV, perhaps not a death sentence anymore but again, good luck explaining to your wife how you got HIV when she has been "your only sexual partner for 10 years".
The list above almost makes me not even want to do oral without either (well 2 and 3 anyway)
