Some may tell you different, but good anal sex is one of the best things a man or woman can achieve sexually. It does not start easily and will take patience, intense dedication and desire to make it to the goal. But your anus has to be broken in and acclimated. Once this is done and you have a cooperative top, you won't find a more gratifying experience than a man's raging hard cock invading, using and filling your hole.
Believe it or not, the thicker the cock the less it hurts. My reason for believing this is because the anal muscles naturally rebel against entry. It seems these muscles fight harder with a slimmer penis, but when the stretch reaches a certain amount, those powerful muscles seem to temporarily give up, making entry much easier and enjoyable. I've told the story many times, but I have a buddy with 6.5 inches of girth. Every time he takes me, my hole lovingly opens and easily accepts his huge thickness. Being FILLED is the most gratifying feeling and amazingly, I'm never sore afterward. I can't get enough good anal.
BTW, clean and internally lubed is another crucial aspect of good anal. Entering slowly is as well.
