Are some people just naturally tighter/looser than others down there?

I think its all about experience. I mean don't forget that the Sphincter is just another muscle. Just as any muscle it will hurt a lot to exercise if you haven't done it before or in a long period of time. The more you train the better it will feel I think I don't think that there is anyone that is naturally looser down there, I think that those who are looser have perhaps loads of experience of it
