I have tried it before and it does raise the feeling and it makes me cum more. But some idiots try it without lube and it hurts, duh you have to put something on your finger before you stick it up there. It isn't for every guy, but some really like it. There are guys at my school that even put their cocks up their friend's ass (a guy friend). Wouldn't that hurt!?
Music is... a higher revelation than all wisdom and philosophy.
