Help! I need ideas!

As much as I HATE Valentine's, I decided I'm going to do something for my boyfriend. We've been through A LOT in the past 2 1/2 years and I just want to do something special. Lingerie maybe? I don't have 1 "sexy" piece of clothing so I have NO clue where to even start or what to get. I was thinking a boudoir shot, but being poor college kids there's no way I spend 200+ for pictures. I looked into diy, but I'm not one of those 21 year old love taking pictures or even "selfies" and it seems super complicated. HELP!!! Please! Any ideas or....really anything is appreciated 💝
