I like Fossil-SCM, so https://chiselapp.com is good for that. But if you want to stick to Git, Forgejo is the best open-source offering (and Codeberg is the most prominent instance). If you want to tread far off of the beaten path, https://hub.darcs.net might meet your needs.
We’ll all benefit once the forgefed project is done, and Forgejo/Gitea/Gitlab can all interact with each other.
It can’t be explained directly, by itself. They’re part of a bigger picture.
Straight men are attracted to women on the whole - legs, arms, waist, face, chest, back, it’s all good. Whatever force it is that makes us attracted to women, it’s not something that we chose or decided. We just do.
Since boobs are a sign of femininity, they’re attractive to us on exactly that level! They fit into our idea of what women look like.
