Why do men think it feels better during sex to not wear a condom?

why would it even feel that different espicially if you used one of those thin condoms? if anything you would think it would feel more different for the woman than the guy
Condoms simply desensitize the penis to a certain extent. They can also chaff and rub the wrong way, which can be painful.

You can get around this though by doing kegel exercises to strengthen and tighten the muscles around your vagina and have your BF put lube on the inside of the condom. He probably wouldn't even notice the difference.

From my own personal point of view the reason I don't like condoms (I use them anyways of course, don't need kids) is because the rubber band at the base basically strangles me and even leaves bruises sometimes. You might think "well get bigger condoms" well the really big ones are too big and the large ones are not any different (other than lengthwise) than regular condoms.
