If you are rotating 4 ladies and they are rotating their own line of dudes, there is a high predicability of catching something. When I dated a few at a time, all was great until I received my first STD. I'm out. If you like to play Russian roulette, go for it. I subscribe to the Donovan Sharpe theory on how to keep your lady in line and knowing what's up 24/7. Check it out sometime.
Never said marriage, I just said relationships. I'd never get married. Too much to lose. Things on the west coast may be different than the east coast, but yes, cheating is prevalent on both sides. A dude needs to be high SMV and keep their b itch in line or toss them the first sight of issues. My point is 100% valid, you choose to see it through the way you want, which, again is fine. There are risks either way, however, the life you live is much more dangerous health wise than the relationship route. This, of course, assumes the lady is worth the relationship route. Most are not, and most will fail. However, it's still better than risking getting an incurable STD or a highly antibiotic resistant STD. Dude, I see it all the time.. It's my day job.
Math doesn't lie. If you are f ucking four ladies, and they are f ucking two or three dudes, those dudes are also f ucking other ladies, etc. You are bound to catch something. Chlamydia, Gonorrhea, and Syphilis are now on the last level of antibiotics. After they get resistant to these, people, in general are f ucked; and not in a good way. New antibiotics are at least 4 years out, even with an FDA fast track. If a person is not cured, they are under State quarantine and are basically a prisoner. Happened last year here in the US and in the UK. If you think f vcking all these ladies are worth that risk, knock yourself out. It's not, and you need to get your head examined if you think it is. This is not the 1960's - early 2000's, and you are not Wilt Chamberlain. Aside from Herpes and HPV, Syphilis and Molluscum contagiosum are able to be transferred from skin to skin contact. That means, even if you are receiving oral sex with a condom and using a condom with vaginal and anal sex, you can still catch one of the four above anywhere else on your body.
Dude, I went to school on this stuff and wrote a paper on it. You have no idea what you are talking about; medically speaking.
