How long should I wait after ACL and meniscus repair before I can be intimate again?

Ok, so I'm having a ACL and meniscus repair done on march 5th. But what I want to know.. is how long after that should I wait until I can be intimate and stuff with my girlfriend? I mean.. I'm thinking like 2 weeks? We're both just kinda curious how much is TOO much strain on the knee... so we want to see. Any ideas?
