Reason #1: You Might Like It
"Is it cold where you are? Then I have a fun suggestion for you. This Winter, grow yourself some fur.
In all seriousness though, if you've never let your body hair grow before and are nervous or apprehensive, I'd definitely recommend giving it a go in Winter! The beauty of stopping shaving in the colder months is that you're covered up more when out and about, so your lil pittens can be sheltered from the world for a bit. You can have some nice private bonding time just the three of you before you have to do the sometimes nerve wracking thing of showing them off to the world.
It can take time to get used to and learn to love a change in your body, and you may find this easier to do in private. Get up in the morning, stretch in front of the mirror, perhaps you notice the hair and it makes you smile, or maybe you're not quite there yet — that's okay! pull on a long sleeve top and give yourself some more time.
Societal views on female body hair are very slowly starting to change, which is amazing, but I won't lie to you and say you won't face any negative responses. It's much easier to handle that negativity when you have already personally developed a loving relationship with your body. When you've learned to be confident in it and see the beauty in it, hair and all, you'll feel much more ready to face the world, arms outstretched."
