Actually I did do it myself for a long time and seemed ok with it, then I missed the closeness of another person (remember separate bedrooms for like 6 years). I realized how alone I felt without being able to embrace her. That loneliness drove me to the OW more than lack of sex.
If the pill kills even wanting to be touched by someone, not sexually just lovingly... forget it... just kill me now.
You know there are guys who voluntarily castrate themselves. This is totally unthinkable to me, you'd have to be insane to want this. I have a hard time even getting a vasectomy (still haven't done this but almost did this once and chickened out).
