Agree entirely with Lonely720 and ATruckersGirl...I enjoyed sex for years before my husband came along and rocked my world with my first orgasms via oral and intercourse at 32. I'd had plenty of manual pleasure and several partners by this time, but none of them were able to take me over the top. My first orgasm prompted by the efforts of a man was by my patient (and talented

) husband -- oral was the first mindblower. Fantastic. Been the happy recipient of oral before, but don't think I was ever really comfortable with it enough to "let go." With my husband, the comfort and trust was there. And since "letting go," I've been letting go as often as possible...! The intercourse orgasm came next (no pun intended) and took a bit more time to master. But I NEVER didn't enjoy sex without the orgasms. Sure, they're great when they happen, but there's so much more to sex than just the big "o". The touching, the heart-racing, the excitement, the breathlessness... you know???
I'd believe your wife and and not only be proud of your "achievement," but also know that it's likely a result of her comfort and trust level with you that has helped her to reach the stars...
