No man I know my self included cheats because it seemed like a fun idea. We cheat because at some point she got what she wanted (a key, a ring, the last name, or a kid). After that there was no reason for her to keep caring about her partners sexual needs. That however doesn’t stop men from needing to fuck look at mcjagger as a prime example. Men don’t want to throw away their lives because their wife doesn’t care. We don’t want to start financially back as square one. So we find some sweet little thing in the side to take care of our needs. So if your man ever cheats on you look at your self for being a failure of a partner and know he only did that because you gave him no choice. Sex isn’t a want it’s a need.
