A person who always wants to take and not give anything while in the act of having sex. This may be someone who forces his partner for a blowjob, handjob, or positions which requires no participation from this person (Like woman-on-top) and won't do the honor to satisfy his / her partner.

This comes from the popular word couch potato, basically describing someone who is lazy, sitting on the couch and watching TV (yes, without bothering to entertain the TV set once he's done)
Kate: I left Joe 'coz he was such a sex potato, I was completely tired.
Mary: God, that must be like slavery! Glad you left him. Date an athlete this time

A person who wants to spend every moment in the house having sex. Usually happens in the first month of a relationship, or soon after becoming sexually active with your partner. Not to be confused with a couch potato, a sex potato often breaks to eat- rather than eat during the act.
Laura: "Have you seen Mark or Beth?"

Rob: "No, Last I heard they were at home having sex, but that was 2 days ago"

Laura: "What a bunch of sexpotatoes!"
