I'm going to have to go with bad idea, not an absolutely horrendous idea mind you, but not the best option IMO. It seems to me (and goodness knows I'm no expert) that you should feel relaxed enough around your partner to not feel that medication would be necessary. Secondly, it might make your partner a bit uncomfortable, as if they aren't making you feel comfy enough on their own, or that they would be somehow taking advantage of you. That's just my two cents anyway, but I reiterate, I'm no expert.
