Stretch marks...

I’ve recently been noticing my stretch marks. It’s tough seeing my body change. My boyfriend of 3 years is so loving and says he loves them and often kisses them (if I let him see). I’ve actually had them longer than I thought, but they’re actually more prominent and a little more red. They’re on my inner thighs and butt and outer thigh closer to my butt. Ladies... how do y’all A) deal with them and B) not feel embarrassed by them (esp. w/ your man)??
