Sex etiquette, any thoughts?

Sexual encounters, like all human interactions, surely go best when common courtesies are observed. My general rule, just a variation on the golden rule, is that the better I can make it for my partner, the better it will be for me. Sure, selfish motivation. Do you have some specific ideas, practices, or pet peeves, in the realm of sex etiquette?

She gets an orgasm before I do.

Some stuff from advice guides. Some applies to new relationships, some of it should also apply to established relationships.

• Personal hygiene: be clean, fresh breath
• Foreplay isn’t an option: Learn the art.
• Oral sex is reciprocal
• Don’t hum while giving oral sex for at least the first two months of a relationship.
• Never push a girls head down if you don’t want teeth, guide and coax – don’t force a BJ
• If you are nearing the finish line, announce. Never ejaculate when she is giving you an oral unless you know she likes that.
• No distractions: Avoid texting or reading emails
• Please her: If you’re a guy, finish last or keep going. If you can’t keep going, rest for a few minutes, try alternatives to help her climax.
• Communicate - Experiment with permission. Vocalize what feels good
• Ask before anal penetration. Never try for the backdoor with a warning or discussion
• Ignore it if your partner farts or queefs - unless they laugh, then laugh with them.
• Don’t compare your partner to others – keep it to yourself
• No means no - even if you've done it before.
• Don’t fall asleep afterwards. It doesn’t end once you’ve finished. Aftercare for both.
