Lingerie for my FWB ?

So I’ve been messing around with this guy that lives above me. We were just friends before we starting hooking up with each other. We only hung out couple of times with each other, but with my ex bf there too. We started hooking up after me and my bf broke up. ( a little background)

we been hooking up for 6 months now, his parents is actually my landlords 😅 lol

Anyways his birthday just past and Valentine’s Day is coming up. is it wear for me to wear a lingerie for him? I just kinda wanted to spice things up a little bit . Lol

I asked my friend about it and she told me she thought it would be weird because he’s not my bf..?

And would you guys think he would think it’s weird for me to wear lingerie for him?

LOl I didn’t think it would of been a problem until my friend said something about it.? What do you guys think?
