Hi Theamos, so yeah condoms may stop any STI's & stop females from getting pregnant 98% of the time! but the material stops the skin to skin contact & its a lot better feeling without them. defiantly not as safe without them though.
I think another reason is, it takes away from the moment somewhat, you have to stop, open the package & unroll it onto the penis, sometimes it doesn’t go on easily & just seems a little awkward & unromantic. However, I almost always used one & felt it didn’t really reduce the sensation that much, and if it resulted in taking a little longer to ejaculate, that was actually a bonus...
