vaginal orgasms?

Hi. I'm wondering if it is a myth that if one only achieves orgasms clitorally that they can achieve them vaginally? I can't seem to get there during sex, thought it sure feels pretty good. I'd love to do so--is there something I can try? Someone told me it comes with age (I'm early thirties though). I just figure it'd be good to know so I can stop hoping it might come along someday or do what I can to make it happen. Thanks! Tweet
