Where are all the Penangitess?

Hi all! Hoping for some advice from experts :[

I recently got a male glider (roughly 1 year old) to teman my female glider (very tame, 2 year old). The male glider is okay, bonding with me going okay so far.

My problem is ever since he joined the family, he's been chasing my female glider non stop ONLY trying to mount her and mate with her. She always crabs and marah him back (obviously not in the mood). At first I thought it's because maybe she's in heat, but it's been 2 weeks and still all he wants to do with her is mate. No playing or just getting to know each other. I started noticing some small bald patches and possibly wounds? But no blood...on both gliders too. Are these mating wounds? The girl has a small one on the shoulder, the boy has a long line right above his tail.

Is this normal when a male suggie meets a female suggie for the first time? The female suggie is fine with him if he's not trying to mate with her or minding his own business, so I think territorial-wise everything is ok. Eating also ok, they don't fight over it. Surprisingly they sleep in the same pouch too. It's just this mating issue! Any help is greatly appreciated tq!
