What is something undeniably sexy about your partner? (F31 M33 here for reference)

I recently have started noticing how small things about my husband are EXTREMELY attractive to me as of late. The way his hands look/move when he drives with one hand. His arms and shoulders…And most recently His facial expressions when we have sex. Like his face during that has this…Idk almost angry but powerful/dominating? look. OMFG. Im so used to keeping my eyes closed a lot of the time cuz im extremely self consious but I happened to open them the other night and i saw him looking down at me and that was it. That look was all it took. Am I crazy or what?
