I'd venture one of the best ways to go "pussy free" for both husband and wife is strap-on sex. You (the man) wear a strap-on harness with a dildo the size of the bull-cock your wife prefers. You can be chastity caged or bare and throbbing, but she gets an amazing pounding, possibly multiple orgasms, and you get a good workout since you're going to be thrusting a lot longer than usual...where your cum ends up remains up to her.
