Should I expect a post-sex phone call?
Kerner says that even in this modern, men-and-women-are-equal world, women should still expect for the guy to call them the next day. If you’re up for calling feel free, but really the ball is in his court.

Does oral sex have to be reciprocal?
Fair’s fair and if you expect to receive, you should probably expect to give.

“I don’t think any woman should settle for a sexual double standard, where she’s the only one giving, and I think the reverse is also true,” Kerner says.

What’s more polite—spitting or swallowing?
Etiquette experts agree that neither is more polite than the other; it’s really what you want to do that’s most important and guys should respect your decision.

Is it rude not to kiss after oral sex?
Mitchell says a quick swipe of the person’s mouth on their arm should solve the problem.

Are there any rules for hygiene?
It’s always nice to be clean and don’t be shy about telling your partner he needs to suds up before you get down and dirty.

“A lot of women have told me that while penis size matters, penis cleanliness matters even more. In general, a woman’s vaginal area, assuming there are no hormonal or bacterial problems, is a pretty self-cleaning system, so there’s not much that has to be done. If you or your guy worry about hygiene, then take a shower together before,” Kerner says.

How can I start that awkward “have you been tested?” talk?
“In a very unemotional way say, ‘You know, naturally I’m very concerned about STDs. Have you been tested?’ Now if you haven’t been tested yourself then you don’t have a right to ask that question,” Mitchell says. “If the partner refuses to be tested, then, without any judgment, say, ‘We better back off until you are tested; I would just feel better that way.”
