I think I would like the idea my husband WANTED to get one and use it on me, cause it says something interesting about his sex drive-always wanting to try new things, keep things exciting, a little adventerous. For that reason alone, I personaly would like the idea. His enthusiam is what would sell me on it , and allow me to enjoy it.
It was me who bought one about 2 yrs ago -when suddenly My sex drive exploded & he was having trouble keeping up with me , but in all honesty, I didnt care to use it , probably only did 3 times total. I bought a vibrator and a dildo, liked the dildo better, but absolutely no comparison to the real thing. I do not care for doing it alone at all.
Once He used it on me, I asked him too, and for me, that was just not a very passionate experience. He was NOT "into it" the way I think the Poster has in mind -to use on his wife. If he was, it would have made a big difference. My husband has absolutely no desire to experiment with sex toys, he wants me to use him, he always says he wants me to use "his toy", which is GREAT- I am not complaining, as I do prefer that. But still the zeal of the one who wants to use them, I believe that makes or breaks the experience -for the receivers pleasure.
Even if your wife may not originally want to try them, the way you present it to her, well, I believe this can surely "enhance" your sex life.
