I suppose you're husbands beard growth may be for any number for reasons, and the way you responed will depend on these, you're own cirmstances, health, beliefs and views.
But I wondered if you'd considered the possibility that for some men it can be a religious thing? Or even a cultural preference?
My husband decided to stop shaving as he considers it a Biblical principle, for the same reason he later cut his hair short and asked me to grow my hair long, (as well as wear a head scarf when in prayer or public worship.)
I was surprised at the request, athough I knew scripture to teach about these things. (The not cutting of the corners if the beard, not nessary to the same extent, as that was a old testament law, for the people if Isreal.) I didn't know many people who practiced these things, I think the principles represented in scripture are more important than outward appearance and in personal preference, I didn't really like the look or feel as much on him and preferred his hair a wee bit long and floopy.
But I know his motivation is to houner God. So out of respect (for God and husband) decided to accept this change, was happy to do as he requested and began to understand his belief that these outward symbols still had a significance.
Anyhow as his beard gets longer it seems to get softer, especially after he started to put coconut oil in it. I also found I enjoy having long hair.
As to the kissing thing, it does feel quite different, and to be honest I used to really very much dislike it as I experince sensory overload/integration issues. I did get used to it. I knew I wanted /needed to for the harmony of the marriage. I suppose if he had had a full beard from the wedding day I'd not have known any different. He is a good looking man with or without a beard, even with the short hair and we have a loving relationship, so all worth it.
