If you have it with clean people safely to not get an inflammation or infection yea and if you limit your partners yea If you have sex with THOUSANDS of different people ALL the time;-----> yea no not really Your not just taking your sexual history into account but theirs and every single person they've done it with as well. You can get a UTI from having sex ONCE as a virgin WITH a virgin (you also can with aids/hiv tho thanx to blood tests thats far less likely) Stuff like Hep C doesnt even show physically and herps when ur not in an outbreak mode also doesnt show up physically. Yea i kno they blood test and screen ppl; guess what----> you can pay to botch a drug test; you can also pay to botch a blood test
