From a biblical context, we’d have to go back and read Genesis 2: 18 - we know that God created his creation accordingly and since Eve (female) was made to be the helper for Adam (male), this joining was evidently going to be passed down through generations, right down to us who are living in the present times.
So the question: why do women like men? It’s in our DNA to be attracted or drawn to the opposite sex, (because of what we read in Genesis). For some Christians they are content on being single which is fine (as mentioned by Paul the Apostle) and, for others they desire companionship.
But I’ll answer your question like this instead: what do I admire about a man?
I actually see how they fit into the equation of being in a marriage and having that specific role of a Christ like man. There are certain qualities that only a man can do that a woman can’t, such as being the leader and headship in a family. Another quality would be the ability to protect a woman or his family not only physically but spiritually - we can find many examples of these men in the Bible i.e Abraham, Hosea, Jacob. Another quality is that men aren’t so easily scared (apart from the odd ones who like me flinch at creepy crawlies!) but most men I’ve come across in my lifetime are built to not fear or be scared of things, people, or situations. There’s almost another layer of “Superman like powers” that men hold - which mixes in well with their protection nature.
I can list many other reasons but I think I’ve gone too deep already with answering the OP.
