Actually we sort of agree.
Though typically (but obviously with good reason) your interpretation of biological function is from the point of view of modern human and all the conceptually driven juxtapositions of base function and thought constructs therein.
So I say chemical signalling and you say love.
Perhaps I am too unemotional.
And like I said to you previously on DebateArt, recreational sex and procreational sex are basically one and the same...Though who what or how one achieves satisfaction recreationally these days, is well explored.
Further...Sexual reproduction is not exclusively the remit of the Animal Kingdom and so by implying that sentience is a key factor of sexuality you do somewhat admit that there is a distinction to be made between base function and overthought.
And thanks very much for the biology lesson...Reminded me of my biology teacher when I was 13 or so.
And as I got older, I realised that my body had been stringing me along all my post pubescent life...Still tries to.
