A way to have sex.
Unlike vaginal or anal where you penetrate the vagina or anus respectively, or oral where she sucks you, or tit where you fuck her tits like its ass or poke her nipples; Optical sex it where you pentrate her eye.

You push your hardened dick into her eye and proceed to do her. Her eye must be wide open the whole time. The act is finished when her eye is covered in cum.
John: What type of sex did you give her Jim?
Jim: Optical Sex, the one where I fuck her eye!
