(Via his shrink, post the break-up of his long-term relationship, in which the gender of the other partner is a mystery to me. Potentially worth sharing as gay guys always seem to know lots about men that women should know...)
1. Never refer to your partner as "my husband" or "my boyfriend" when talking about him with other people. That diminishes the relationship. Just call him by his name.
2. Close the door when you pee.
