Q I’m a young heteroflexible guy who’s been a “sugar baby” for a handful of wealthy older guys. I love it! I get money, I have fun being with them, and the guys seem to like having me around. The problem is that I just got with a new guy who’s really great except for one thing: he’s HIV positive. He says that his doctors predict he won’t have a shortened life span and may not even have any symptoms that would make his life uncomfortable. I like the fact that he told me, and I’m open to being with him sexually even though I’m HIV negative and want to stay that way.

A It’s pretty simple, HIV: Sex acts that expose you to his semen and/or blood are definitely unsafe, and sex acts that expose him to your semen and/or blood are mostly safe. Rimming you, blowing you (even without a condom), getting fucked by you (with a condom)—all very low risk for HIV transmission. If he’s on a drug regimen and his viral load is undetectable, HIV, your already-low risks of being exposed while, say, accepting a blow job (and a check) are even lower. The risks aren’t nonexistent—all sex acts carry some degree of risk—but if the risks were any closer to nonexistent, they’d be sitting on nonexistent’s lap.

Q I’m a 24-year-old straight guy. I’ve been with my girl for three years, and things are great—great sex life, great communication, etc. We have lots of sex, but for the last year or so she hasn’t been on birth control and we haven’t been using condoms. We’re not against the idea of a child, but we aren’t currently going for it. I was always told that pulling out was a 100 percent ineffective method of birth control. So my question is, I guess, could there be something wrong with one of us? How could we have unprotected sex for a year without getting her pregnant? We both really want children eventually and are worried it might not happen. —Sent From My iPhone

A Every time I’ve watched needle play in a dungeon-party situation—watched with my hands clamped over my eyes, peeking through the small spaces between my fingers—no one was being stuck with rusty needles by dirty-handed brutes. All the public needle-play scenes I’ve witnessed were ostentatiously sterile affairs: these kinksters, some of whom were trained medical professionals, made a big show of using alcohol wipes, cotton swabs, latex gloves, and clean sharps. I think it’s fair to ask this girl for more information about her blood and needle experiences, about the safety precautions that her partners took, and about how recently she was tested. But rest assured, ER, that the most effective STI transmission routes involve sticking dicks in people in completely vanilla situations, not clean needles in dungeon-party situations.
