DH wants to come to every appt

So my husband wants to come to every prenatal appt and be present in the room. Great in theory, but in reality there are some things I'd rather spare him (I.e. Discussing increased discharge, etc. with my doc). Does anyone have advice as to the best way to tell him I'd prefer him not to come without hurting his feelings? Note: I've already tried approaching it from the "no ultrasound this appt. do you really don't have to come angle".
