I think a man owes it to himself to marry a young childless maiden and attempt to create an Ozzie & Harriet family, with the level of ejaculations with his wife like Hef. Fortunately for the wife, she must be sexually receptive for her to get pregnant, so she is motivated early on to spread the legs. Of course, it is after she has had all the children that she wants that she does not see the need for sex.
So the proper path for a man is to simply stay in the marriage as long as he is getting what he wants, and then when he is not, he gives a soft ultimatum - i.e., that he is not getting enough action, and he wants to seek other action. That puts the onus on wifey to either start putting out, or realize that she does not want to do her wifely duties, and let him go in divorce. It would not be his fault, because she is the one not doing what she is supposed to do. Then hubby takes the big financial hit and gets on with his life, and has ready excuses not to get married again - already has kids, and doesn't want more, already gone through a marriage that did not work, and that left him poorer, etc.
Hubby would not need to secure good genes and mothering skills for his kids, so he could get a vasectomy and go back to being a horny teenager. He could even hire prostitutes with the full knowledge that sex with his ex-wife had cost him a certain amount, so paying a prostitute would be cost-effective (especially one in a poorer country.) He could get a girlfriend and have sex with her, and even be a common-law husband, but he would be in a position to resist any woman wanting him to marry, and could simply dump that women if she were to try to restrict the sex.
