The simple answer is yes, it can feel good for men. Men have a prostate that is located inside of them and it feels incredible when it is stimulated. It's sometimes called the male g-spot.
You should definitely explain to your wife how you feel. It sounds like it's the first time for both of you to try pegging. One tip I would suggest is to pick a strap-on that is thin and smooth. You could check out some of our Vac-U-Lock options. The platinum line is great. We have some items in there that are specifically made for pegging purposes because of how thin and smooth they are.
Use a lot of lube and really warm up to something like this. Communicate with your wife during the entire process and go slow. Only start with a couple of inches. You do not necessarily have to use the full length.
Agree on a safe word. However, it shouldn't be a word like "Ouch." Make it something that the two of you aren't necessarily going to say when you're both in the mood.
