DaveJ/C_L, The issue is certainly not whether I'm ready or not; I'm ready to hump just about anything that walks by.
I can definitely relate to that feeling.
I agree with the previous comments about the intimacy helping to restore R, so in that respect I would say go for it. What I would be concerned about is getting to that point and having her reaction be something like 'okay, lets get this over with'. If that were the case, I'd probably back down and suggest that it can wait and settle for some cuddling.
However, if it gets to that point with sparks flying and heavy passion, then by all means enjoy!!
