One of the things that surprises people is the fact that they enjoy it so much..
But I bet you are horny as hell, so don't worry it's normal to enjoy it. You may already have tears in your eyes from the procedure, but that's natural, don't worry about it. Enjoy it as it's just you at the moment, but also think about how great it would be do to it on an actual dick. And how proud you will be that you were able to do it.
