About four years into my marriage I came to the realization that our sex life sucked. We never made it to a fifth year, I realized our problem, accepted the fact it wasn't in the cards that we would ever fix it and rather than risk the possibility of looking back on my life when I was an "old man" in my sixties like I am now, only with the same regrets as you have, I sucked it up, bit the bullet financially, and got the fuck out of my marriage and I have been happily fucking my brains out ever since.  

 
One day my dick is either going to fall off or simply quit working, but until that day I am not going to let the fear of some disease that has less than one chance in a thousand of killing me even on the off chance that I catch it in the first place from enjoying my life to the fullest. For all I know I might get hit by a fucking bus tomorrow, I am not going to waste tonight worrying about it. I plan on getting laid tonight, tomorrow and pretty much every other day as long as my dick works, and I encourage everyone else to do the same, unless of course you are already in one of those seriously high risk groups.

I haven't lost interest in sex (I guess that is obvious because I am here) but it is hard to retain interest in sex with the same woman for decades even if she is receptive to sex.  On the other hand marriage is generally an economic benefit (and divorce is an economic disaster.)  So how do you split the baby -- get lots of variety and retain the financial stability of marriage?  I envy guys who have open marriages.  But you need an certain kind of woman for that, a rarity.  That leaves deception.  That's the path I am on, for now.  COVID is gonna get you or it isn't   I don't think visiting escorts is going to matter, just one more person in the dozens per week or month you come across (ha ha).

Great advice.

I am in my early 40's and better get to fucking more before menopause hits. Thanks for sharing! xoox
