This isn't a guy's perspective, but my husband and I always had a pretty good sex life until my illness. After radiation and chemo, though, I just had no libido for about 3 months (and like Minnie I didn't feel very attractive with the PEG, and in my case there's also a dented breast from a lumpectomy, it's taken me many months since to learn that when he's in the mood, that PEG tube and the dent in my breast don't even exist for my husband! )
When I started to get the urge again was one of the first signs to me that I was really *really* getting better. I'm grateful my husband was kind and patient through most of it, or at least appeared to be at the time!
