Hotter than Dutch love.

Yea dutch oven sounds right.

I inveted a saying of my own along the lines of hot weather.

its so hot that i'm sweating like a rapist.

basically means to excrete body heat in the same manner as if someone had been forcefully restraining a struggling individual and commencing intercourse.
if you feel the need on a hot day, feel free to spread the lovin'. use my saying fancy free
