I have been lucky since my wife and I have been sexually active until 5 years ago when she turned 55.. even with all the porn and lubrication it mostly turn into a painful affair for the both of us. then she proposed that i go get it outside but don't bring it back home.. which I have been doing. still I feel very guilty everytime i succumb to my lustful desires.. no wonder those rich men's wives will always handpick 2nd wife for their husbands back in the old days..
