It's definitely not a black and white issue but, it's more about playing your odds. Ask yourself a simple question. If you are a person who desires a deep, long lasting relationship, do you feel you would statistically be better off hunting a person who tries to reserve their passions until they find someone they deem suitable to them, or a person who screws everyone that is willing?
For the latter, I seriously doubt most people who nail everything that has a pulse is really seeking a deep relationship, but they may end up finding a person they end up admiring assuming they get the time of day to even express that sentiment, and that's the problem. People lie, cheat, and fool others or even themselves to try and mold themselves as something they may respect but really aren't.
For me, I had a particular challenge because I wanted a girl who shared my refraining values and commitment ideals while also not being a bible thumping sheep that refrains out of fear of something living in the sky. We all have our personal challenges, but when it comes to love and relationships, you shouldn't cut off segments of people, but it's probably smarter to narrow your views or focus to people who are obviously like minded as well.
I like stability, a routine, and a little spice here and there to keep the tedium at bay, some don't, I'm not going to try and find a girl and try to convince her to do things my way, i'd rather her share the values and not have a past she regrets shutting down due to us not seeing eye to eye but maybe still wanting to try and make it work.
