Wearing stocking fetish

So recently I’ve been talking to this guy who I really really like. We’ve become very close with each other so he decided to let me in on his biggest secret. Now typically I wouldn’t have posted his biggest secret in the internet but I’m just confused and feel like there’s gotta be some girl out there who can comment on this and give me support. Okay so my guy likes to wear female lingerie. Panties, stockings, nylons, full body fishnets. He says he’s only had sex once ever and never tells anyone about this because he is extremely insecure. I really don’t think it’s that big of a deal, I truly believe he is straight (maybe I’m an idiot but idk). I just don’t exactly know how to react/ handle it. I adore him enough to push past it and I’m even willing to go beyond that and maybe let him experience his own fun. I just wanna know is there anyone out there in a similar situation as this? How’d you work with it? Thanks.
