My BF thinks it's hot when I wear a pad during sex & like all the time..?

Okay, so... my bf recently started to like it when I wear a pad and asked me to wear them even when I'm not on my period. I just thought it was funny at first, but he really like it now and asks me to wear a pad all the time when we hang out or when we go places. He likes to look at my butt and panty lines when we're out especially if im wearing a bikini and a pad. Also.... he likes it when I wear a bikini panty and pad during sex too. So, now we're having sex and i'll have my butt up in the air with him behind me WITH a panty and pad on. I wear stayfree classic pads, so they're a pretty good size pad. Sometimes he pulls out when he's cumming and cums all over the pad while i'm still wearing it then wants me to keep wearing it while I suck on him more. It gets worse because when I cum, I leak allot and the pad soaks up everything. It's totally messy but idk. He likes it and I want to make him happy. Does he have a fetish or something?? Does anyone else's guy out there like this?? I'm wearing pads all the time now haha :(.
