I am scheduled to have surgery on Thursday.
2 weeks is probably a good time frame. I think it was about that long for me. I know my husband was very hesitant and there wasn't much touching above the waist yet, but it was fine. The sensation in the nipples is definitly different, but different nice, so that was good. I kind of remember some throbbing feeling in them during sex and stimulation, but I don't believe sex at any time after surgery will hurt your incisions and healing.
