I would say it was 3 weeks before I felt like I could get out and do some stuff. 6 weeks I was feeling a lot better.....but as for sex...we tried at 6weeks but Ouch. I think it was a while longer before sex wasn't painful.
I do however wish I had started try to do some type of mild working out around 2 months. I still have numbness and it's been 16 months.
Just be careful. You just had major surgery.
