Are men always keeping their options open?

This is not meant to be disrespectful at all so please dont take it harshly. Its just a simple question. Based off of what I have heard (and I have NEVER once heard a man deny) is that men are very sexually and visually driven. Men will always check out women around them even if they are in a relationship or they will fantasize about wanting more from their girlfriend - wanting her to be freakier in bed, have a bigger butt or bigger breast, be nicer or more fiesty or sassy or what ever. Even if they ARE happy with the woman they have, they will always crave the freedom and the variety of other women. Even if they don't physically act on it, they will (from what men say) always be receptive to other women. I may be wrong, and I don't mean to generalize. I know for a fact that this isn't true with ALL women because I am a woman and when I was in a relationship with the one boyfriend I had in my whole life, he was more than enough for me. More than one time guys who were more physically attractive or wealthier than him approached me. But their was always a barrier up, I didn't give any man the oppertunity to prove himself to be better in any way. I shut out all men, I didn't accept new male friends, I got off of social media for the entire relationship and I fully committed and convinced myself that although there were other guys, I (at the time) had found MY guy and shut off every oppertunity for anyone else to come into my life. It wasn't something that my (then) boyfriend asked of me nor did he even know that I had done all of this. To this day he still doesn't know how committed I had been to him. But I think I blocked other men and completely stopped being on the market. Now what Im asking is, how often do MEN do this for their girlfriends? How common is it that a man will meet a girl and block other women who are prettier, smarter, richer, and more popluar than their girlfrien Do men tend to keep their options open more often?
