Ok, so you've been dating your guy for a bit and you have a hunch the two of you are about to get nekkid, perhaps even on your next date. First of all, congrats -- sex is fun. You'll enjoy it. But it's easy to take a wrong turn in the sack, so whether this is your first, fifth or fiftieth time doing the horizontal bop, remember these few simple rules for keeping things light and lively. These apply to you, too, guys, so pay attention.

1) Don't mention any other sex partner. Ever.

"Touch me there. Oh yeah, that's it. My ex used to do that." It's like he's suddenly there with us. Instant limp-on.

2) Don't barf on him

You did tequila shots all night and now you're ripping each others' clothes off. Fine, unless you can't hold your liquor. Once in college I was making out with this young lady after a party at which we'd both consumed copious amounts of alcohol. Things were getting hot and heavy when suddenly she looked at me, smiled, and said, "Hang on," then turned her head and puked all over my floor. Maybe it was my kissing, I thought, until she wiped her mouth and was ready to go some more. Uh, no.

3) Don't laugh at his junk

My friend Deb dated a guy who was a bodybuilder, so the first time they got naked, she was shocked at his lack of equipment. It caught her so off guard that she did the unthinkable: she laughed. Just a little laugh, and then she caught herself, but it was too late. The guy got pissed and left. She felt terrible. The lesson here? Guys can be sensitive about their junk, even guys who are hung, so the first time you're about to get it on, be ready for an anaconda, a garden snake or anything in-between.

4) Don't get distracted

Two weeks ago my buddy Tom said he and his wife were doing the deed when he caught her looking over his shoulder watching TV. "Why the hell did you have the TV on?" I asked. "I dunno," he said. "It just was." Oy. You can't really blame his wife -- Conan was on. But we all want a bed partner who's in the moment, so if you want a good sex session, get rid of all distractions before getting busy. In other words, Tivo that shit.

5) Don't scream like a maniac

Sure, guys love a woman who's vocal in the sack, but there's a limit. If you start shrieking like a porn star, it's a little disconcerting. We're glad it feels good, and we hate to hold you back, but the neighbors are gonna call the cops if you keep that up, so can you bring it down a notch? Thanks.

Ok, so there's five. You'll get the other six later. I know, false advertising, sorry.

Good luck.
