You should tell them this. It would work.
Do you really think it'll help?
I would totally open a door for you and buy you coffee/dinner, Channy.
And I hate the idea of "putting out" in general. Just have sex with me because it's awesome and we can have fun.
I hate the idea of earning anything from someone I love, let alone the deepest a relationship can get, sex.
Having to 'earn' sex persay, when in a relationship, I agree, is just taking the piss. But I think men give us too much credit in being complex creatures who are high maintenence. Some of us are as simple as you are.
