I've never had a problem with any woman refusing me sex. In fact, most often she will want at least as often as I do, if not more.
I believe at least a part of the reason for this is that I would never put up with it. I might accept the "I'm tired" excuse once or twice, but by the 3rd time I'd be starting a fight. And if it got to a 4th time, I'd literally be starting a fight every night over the issue. If this went on for a prolonged period of time in marriage- say 3 months or more- it would be time to go to war. Withholding money, refusing to clean up after myself, even quitting my job would all be on the table.
But the ironic thing is that I've never had to do there.
Many women also end up marrying Men they absolutely aren't attracted to or just disgusted by only so that they can have a Man to support them as their SMV is on the decline.
So all those excuses end up coming up because they were never into their Husbands in the first place. Unlike their past Old Flames who they really were attracted to.
