This is actually one reason I do believe that prostitution should be legal in the US. It can allow for men to have some place to go.
I have always loved the quote from the old lady in the movie "The Best Little Whorehouse In Texas",
Dora : My Frank, when he was alive, used to go up there every Saturday. I took it as a blessin'. Of course, things were different then. Nowadays women enjoy doin' that sort of thing themselves. At least, so I've been told.

I would say given the age of this movie/play that the idea that men could seek out a prostitute, approved by his wife, is not that new or farfetched. I would actually prefer this if it came to the point where I could not fulfill my husband's sexual needs, and just would hope that I could still fulfill his emotional/companionship needs. Of course, this would only be if prostitution were actually legal.
That all being said, I do think it is wrong to say that sex for all men or even most is a need like food or expelling waste that has to be met (and talking full sex here) every month or similar time frame. Sailors go months out to sea, many not having sex for that whole time, whether 1 month or 10 months. Soldiers and Marines can spend a year or longer on deployments. Some few will have sex, whether with women on the ship or base with them or in ports. Of course, some ships do not have women on them nor do they enter ports for up to 6 months. It really is a matter of self control. While it is important for a person's spouse to recognize their emotional and sexual needs, it is also important to discuss why and ways that you might be able to help the other if they are never in the mood (which could indicate a problem in itself). It is also important to recognize that it really isn't right to put your spouse at risk or risk hurting them emotionally to fulfill your sexual and/or emotional needs. If you love them, seriously sit down with them and have a serious conversation with them about your feelings and open up. Either they will eventually listen to you or they will leave you, but there would be a lot less hurt if you talk to them about it and tell them how you feel. Maybe even tell them that you are thinking about having an affair with someone else, because it has reached that level.
