Personally, I am with the majority. Hormones are not necessary to snuggle and kiss. Although the desire may be limited by other factors. I'm in my upper 40's and underwent a total hysterectomy around 6 or 7 years ago (for medical reasons).

I definitely enjoy sex a lot more now than I did prior to surgery. It has been uncomfortable for me a time or two, which quickly taught me that decent lubrication is absolutely necessary. K-Y Jelly works great. Also: taking things slowly and comfortably for her helps ~ more than I can express. It can feel pretty scary when you're used to intense pain.

On that note, I also agree with Middlemarcher's input. Be direct, but gentle, when you approach your partner about the issue.
