Based on that one photo I think your tortoise is a male with the tip of the tail missing or deformed. Female Hermann's, regardless of subspecies, do not have that much of an open spread of the anal scutes as males do.
So I should stop calling her cherie and maybe start a more masculine name? The other one used to mate with it a lot (have calmed loads) is that normal?
If it's two males it's not mating, it's domination. Although it looks like a male in the photo, a few other photos would tell more for certain. How does it compare in appearance in the tail/anal scute area of your known male tortoise? How big are both (straight line carapace length)?
I agree it looks like a young male My hermans looked female but he started ramming, i looked up pictures and noticed the v shape on males where girls tend to have a u shape his tail was still small but it started me thinking he was male i was right he now has the long tail
