This is an important one, and it really belongs up above the black sweater rule: turn the lights out. If you’re getting busy with someone for the first time, it will take a lot of the pressure off to turn out the lights. Because everyone else self-conscious and when you’re getting it on for the first time in any degree, you need to not see what’s going on across from you. Don’t get nervous! Just turn the damn lights off.
This deserves to go above the sweater rule because if you follow this rule, sweaters don’t really pose an issue.
Please note that this rule may not apply to visual learners.
