What do you find most arousing?

I was chatting on a cuck site earlier and me and a guy were asking some interesting questions.
we were talking about what particular elements of sexual activity get us the most aroused, and we had to name 2.

his was, panties and humiliation which got him the hardest.

mine are, semen on female skin and eagerness.

eagerness is so erotic to me, from a female acting like a dog in heat to the eagerness a guy shows in his rock hard erection...so wonderful.

if anyone reads this, and can be bothered, please add 2 of yours in the comments.
