agreed. but it's not his fault. i've been with lots of hot women who just starfish. it's an established term. i'm sure you're familiar with it. this is very common for women. women don't share the same desire for sex that men have. that's why women get paid 3 X more than men in porn. women also don't care about size (sorry fellas)...
The Urban Dictionary definition states that a Starfish is: A female sexual partner who remains 'unmoved' during lovemaking, physically non-responsive (like a ….). ... It's a horrible term, but if that's you (or you're having sex with someone who “starfishes”) here's why this happens.
