I say ALWAYS wear a coat, unless or until you're married and trying to reproduce ...... and learn how to use them right too. What kinds of lubes, if any are necessary, etc etc. I've become a safety freak in the past year or so. I had a breakage scare (basically it broke when I was already up in her) fairly recently , and this was some chick I really barely knew (bar hook- up basically, so if she did that w/me right away, what's that tell you, right?? ). So, yeah, not only was it a mood kill (we eventually did finish) but it scared me. I kept expecting my sh*t to be smoking in a week or so. But, I went and got a full run of tests at a free clinic where they test for everything (you should all do this if you've ever been unsafely sexually active, IMHO) , and luckily I came up clean. I'm supposed to go celibate , technically, for the next 6 months now, at which point I'm supposed to go there and get one more blood test done for HIV. If I'm still neg at that point then I'm supposed to be good to go again from there. But sh*t I doubt I'll make it 6 months w/zero action. Probably just be real careful if /when my next opportunity "arises", no pun...... ;-)
I'm veering off topic a little here now, but DEFINITELY always wear a coat if you ever get into any of that backdoor action too. Forget what you seen in any porno BS. It's not all good and clean and easy like that. I've tried that , in my life, on like 3 occasions now (and no smarta$$es I was NOT ever on the receiving end ;-) , and I have to tell you IMO it's NOT all it's oftentimes cracked up to be. And without a coat in there you can get all kinds of like "parasites" and stuff too, along with the regular STD's and even of course HIV (though the odds of getting HIV that way for the male are less than for the female). But that activity is just nasty as hell IMHO. I think it's clear that men and women were meant by Mother Nature to do it the way that (most of us at least) do , and not try to use the backdoor for entry.
