hi lapilot'
My uro told me to exercise the fella when he took the catheter out on day 8 (he explained just what tigerfan has already said) but no sex with my wife for 6 weeks. he then set me up with his ed nurse for the next week (I asked if she was cute and he told me she's very nice and she is) she told me the same thing tigerfan and my uro stated and put me on 5mg Cialis. I had my follow up with her today and told me she doesn't need to see me anymore, first time I was glad to hear a woman tell me that.
I like you was starting to get my nocturnal erections soon after surgery (one before the catheter came out that one hurt but I was happy to get it) so consider that a great sign. My wife and I resumed normal relations two days before the six weeks. hopefully you will too.
One possible thing that can happen is leaking during arousal and at orgasm. it doesn't happen to everyone but I had it after my second "therapy session" . it freaked me out until I posted it here and found out it happens sometimes and was advised that it should clear up and it quickly did.
best wishes for full recovery
