1. Maximus lube, for all your anal/vaginal penetration needs.
(We even asked a friend to buy us some and ship it here from the US, because it's so good.)
2. Anal makes for some awesome fucking. Especially when combined with a reach-around.
3. It's okay (and very helpful) for me to fantasize about other people when my husband is working on my orgasm, and he encourages it as well.
4. Remaining utterly open and non-judgmental about my husband's (and my own!) sexual fantasies is one of the keys to our happy marriage.
5. Good vibes don't die young. Oh yeah, and always have a stock of batteries on hand!
