Germaphobe during sex?

I wouldn’t exactly say I became a germaphobe.... but ever since I had my baby, I do not want to have sex as often with my husband anymore. Reason is when we have sex, he touches EVERYTHING! By everything I mean couches, furniture, door knobs, etc...... so I am constantly having to clean these after sex... I just feel its nasty that he does that since our son touches these things too. Not sure how to tell my husband.
