Hey, guys

So far, I’ve been really enjoying everything you guys have shared. Now me and any other ladies can have a reference for what men find romantic to do for our partners. Thanks everyone.

By the way, I should specify that it does NOT have to be a huge gesture. Or even include a gift. Anything which made you (or you’ve witnessed made another guy) feel special is enough.
