I don't think porn anal is anything like real anal. Porn anal is left for the pros, or amateurs who have pro pontential.
Anal is like killing & butchering a deer for meat(anal) instead of going to the grocery store and buying cow meat(regular). It's a little more exotic, but it's alot more work. Everyone should try it at least once for the experience but it's not worth the work. Of course, for me it's more about getting my rocks off than how I get my rocks off.
