First of all, let me state that I am a 39 year old male in a committed relationship. This is the fact that makes me feel even guiltier about my thoughts but I feel I would solicit some advice on how to handle the problem before it becomes a major one.
Let me try to give you a short, brief history. At a young age, I married my high-school sweetheart, (the only woman I ever had sex with or even dated) had kids, lived the life for 11 years of marriage before issues caused a divorce.
