The great physicist Richard Feynman once said “Physics is to mathematics like sex is to masturbation.” This is a view I strongly contest. On the contrary, Maths is like sex with a woman, Physics is like sex with a man.
Mathematics can be beautiful. It's beauty can be a high elegance; regal, almost. Or it might be what we could describe as 'pretty', something that makes us smile whenever we see it (which is by no means an inferior sort of beauty). But either way, I think maths has a distinctly feminine aspect.
Physics on the other hand, whilst certainly not inferior to maths, is very different. It's less perfect, more rough and ready. More likely to bend you over a table. Distinctly masculine.
But if maths and physics are both like sex, albeit different types of sex, then chemistry, with its imprecision and lack of deeper truth, must surely be like masturbation. Masturbation whilst watching particularly low quality pornography.
