My M reaction is that this is the guy v . girl thing on fashion and perspectives . For example , guys me included tend to wear the same damned thing over and over jeans tshirt once is jeans tshirt forever . Girls , well there ' s two layers there from guy view . One is that , for a young guy , any woman ' s body is an exploration and new territory . After that , we find any naughty that is underwear changes to be sexually targeted even when this was personal preference . However given that women change fashion more frequently than men , we kindasorta tend to file these changes under fashion change rather than relationship effort . So , your new undies were girl things rather than for him . I ' m happy y ' all keep fucking us , but I ' m sometimes confused a to why .
