Dear P.,
Sadly for me, I've been experiencing a similar situation since we got married four years ago. I've really struggled through the fears about my body and the anger I felt toward him and his (what I saw as) "with-holding" his attention and affection. I've had some frank discussions with him during this time (-sometimes while slightly drunk and sobbing that I'm fat or maybe he's having an affair...NOT a good idea). I tried everything I could think of to no avail. (I mean, I'm willing to dress like a bunny and tap dance if that's what it takes!!! I'm a team player...) What I've discovered is:
1. My husband's libido is not as strong as mine, and that is ebbs and flows.
2. My HUSBAND is more effected by stress and emotion when it comes to intimacy than I am
3. He has insecurities about his body too.
Turns out recently he's been effected by a strange scar tissue issue on his mighty " Winky". His "trouser snake" gets a little crooked when at full attention and it's somewhat uncomfortable - though not painful. He went to a urologist and got it looked at and it may get better on it's own, or he might need surgery down the road.
But I digress. I actually talked to my OB, a guy, when we were trying to get pregnant and he gave me a script for some Viagra, but this ended up really insulting my husband. We're doing okay now, but not great. I'd still like to be intimate more, and yet I'm coming to realize I may have to fulfill my own needs more often if we're to have harmony in our home. Anyway, I totally understand where you are coming from and I have absolute sympathy for your situation.
