you know, so many comments on here should be being made by the health nurse, and aren't. Isn't it a bit risky to be taking advice from sources that aren't really reliable? And even at that there are exceptions to every rule. Diseases get passed around from intimate contact. Even if BBBJ doesn't pass on the big G, it does pass on other things. Like there is one called NGU, and frankly that can be very nasty too. Worse issues I ever had with a sore PeePee came from a quick BBBJ once twenty years ago. Since then I just don't let anyone do it. Has to be a special gal who there is some trust and experience with.
Likewise Daty can give you some nice issues, so yes, you need to be careful.
as some one said above if you get the fluid through any source into the wrong spot you are gong to have the disease. that is very logical, diseases live in fluids, get transmitted through that fluid so keep it away from your critical places.
Twenty years ago I used to see a gal who always gave me some issue. We used condoms of course, I took it off carefully, but always within a few days needed some antibiotic cream on my precious one. Finally reasoned it out. Never had a shower afterwards, so her liquids were all over my hair in that region. So put your underwear back on and it all gets rubbed around. Now the underwear is contaminated. That passes it on to your critical spot. Stopped seeing her, figured even with a condom it wasn't safe, but really a shower afterwards would have resolved the issue. so now even if a shower is not there, go and dry yourself off, and be careful not to pass it on to to other parts of the body.
Liquid control after the fact is pretty important. You see how gals will take off the condom and only hold it by one point, and get it out of their hands quickly. Well they know it could contain diseases, you need to realize they could too. It is just not STD's but all those other annoying issues too like yeasts, and other flora and fauna.
