Oh please. What happens when wifey goes from a size 6 to a size 20 and only feels like having sex once every couple of months because she's "too busy" or "too tired?" (Probably because she wore herself out eating potato chips and drinking "Biggie" sodas at 500 calories a pop.) A healthy man if he wants to remain healthy needs to clean the pipes on a regular basis, and if he needs to look at porn for a little help under the circumstance that I have described, then the wife has no one to blame but herself. And yes, I feel the same way about men who get a beer gut and show no interest in sex for months at a time.
If your wife gains a lot of weight real men help and encourage them to lose the weight.
Most woman who refrain from sex it's because of the way their husbands treat her.
Maybe after being abused by you she started this. The way you talk it's obvious you are an abusive person.
Real men help their wives. Abusive men cheat and turn to porn.
Hopefully she'll leave you. Bet you 20 bucks within a year she's down to a size 10 and with a real man.
