While it is true that a condom does take away from the sensation of the sex, again I must remind you that there's more than just the physical feeling. You need to be sure that the person you're doing it with is safe to do it with before walking into a bareback situation. If you're not careful, you can end up with quite the problem in the end. It's more than just living with something like HIV, it's also the side effects, the medication costs, and a boat load of other medical issues like co-infection that you have to begin to be more concerned about. Then again, you'd be surprised at what a person can make themselves do when their life depends on it.
