I do not agree. I think humour and sex have similarities. The laugh is a kind of social orgasm. Furthermore, you have the surprise effect, the unexpected... All this sensations may cause both laughter and desire..
Oh yes, I think so too but it is rarely that I meet anyone or read anything that blends the pleasure of both humour and sex together. Your 2-line poems are quite funny, really, and thank goodness, they are noble as well!
