Yes, it will make a difference to both of you. I use a leather cockstrap behind the balls during intercourse with my wife. She loves it and I do too. She loves giving me oral and anal with this on. It makes my orgasms supercharged. She never asks for it but I can tell that she likes it because she gets very frisky when I come to bed with it on.
It may not be easy to introduce new things. I always talk about it with her first. I tell her that there is something that I want to try and that I need her to help me see what it is like. Women like to help men when men ask for help.
Another way is to shop for sex toys on the internet together. Let her drive. You might be surprised what she would like to try.
Have fun.
