Do you ever self-finger?

I'm not saying that it should be an every day occurrence, but every now and then it's a good idea to probe yourself, usually with some body lotion as lube. You'd be surprised at how many nerve endings you have back there. And clenching your ass ring around your finger is good practice in case some day you have some other guy's cock inside you and he wants to be properly “ milked.”
