eheheh you call for aid, and lotr kinky community will answer! okay first buy here a
vibrator egg or rabbit or whatever, for her to do things her own way. If she has a lower sex drive, give her the ability to figure out what her body wants. having her own little orgasm machine might inspire her to try more - and thus try more she shall, with you, of course. and then you go shop together and buy a toy for you both - I would say a ring but XD it's gets a double meaning here. A ring to rule all of them orgasms! oh... I guess what I'm trying to say - talk to her, be attentive to what she needs and wants. The best way to figure out how to make your wife happy is ask her - and then MEMEROIZE what she says to file it for later and whip it out whenever. First ask, then implement. If you remember things she likes, she will appreciate greatly - it applies to the bedroom stuff too.
