This is for the size queens out there.. once you know how good sex is with a guy who has a really big cock, can you ever go back to truly enjoying sex with someone who's small? My wife of 1 1/2 years started sleeping with guys with big cocks about a year ago, and now she tells me she has to pretend to enjoy it if we ever had sex anymore, because she's so used to the much more intense sex with well-endowed men.. is this normal?
