your wife sucks, kick her to the curb.

HAHAHAHAHHAHA

Same as the others said. If she never said anything about it before, fuck her life; she should have told you.

Either she's an idiot for never bringing it up sooner, or you're as dense as a brick for not being able to gauge her reactions/responses.

Tell her, if you had a nickel for each time you have blown your load while thinking of some random hot chick you passed in the street that day, you would be a millionair ;)

Ouch. I'm, well, a virgin, but I know what some women like. Anyway, try to get her to be more truthful about her reactions. She just had an outburst then; faking shows that she cares about your feelings. I think the worst thing a guy can do is flat out ask their spouse what they've been doing wrong, but I'm not sure. I'd save it as a last resort. Hope things turn out better in the future. Remember to put her needs before yours!

WTF, this situation does not deserve a divorce! Just talk to her about it, and try and learn what she likes. It could be very exciting and brighten up your sex life :D

That sucks, but its not your fault. Its really difficult to get some women to orgasm. This is pretty good for you guys though... spices things up. :D Ask her exactly what she wants, seeing as how she hasnt TOLD you for 16 years...

Dudes...love is all about communication and the wonderful journey you have with your partner. Your wife made an insensitive comment that probably hurt more than it helped. I would say marriage counseling.

maybe you should eat her out? just a thought...
