What would you do if your husband bought used panties online?

I was cleaning my husband's drawer when I found panties that were 100% not mine. When I texted him asking who's panties were in his drawer he said he bought them online.

I think it's so gross, he's sniffing and rubbing some other chicks panties on himself.

I told him I didnt like that hes spending money that could be spend on our daughter on some random chicks online and his response was "then can I steal panties? Like if we were at the beach and a girl left her bag open. Can I take hers?"

I feel like this is cheating but I feel like I'm also overreacting!! Help!!
