It feels different for sure and I personally much prefer it without, but that isn't the point here. 

The point is if you have a potential partner who doesn't respect you enough to wear a condom they probably won't respect you in other ways, time to move on

This. Having experienced both with and without a condom, and with many different types of condoms, I can say there's definitely difference in feeling, but I still use them, since me and my girlfriend want to be safe. Just because the feeling's slightly worse doesn't mean it's not still incredible.
