Having sex with someone to prove a point such as your love for them, that you are over them, that you are not gay, or that you are a good lover.
I didn't want to have proof sex with him but how else was I going to get him to stop begging for a date after I told him he kissed like a gay guy?

Any act of sexual contact with an ex after the breakup. Usually involves post contact crying and/or emotional turmoil. Can also involve hate sex and/or proof sex.
Ugh! I just had exsex using my tears as lube and want to slit my wrists with a dull, rusty butter knife.
