I just tried it two days ago anal for my first time.It was actually painful and he was using lube my ass hole was so tight it took a long time
To penetrate.at first it hurts but eventually it feels good

The bottom being fully relaxed and comfortable with a top who is about to penetrate him is key. For the first time, try entering each other while laying side by side.

I would recommend being on your back the first time you have anal sex. My opinion, but the initial penetration is not as painful if you are on your back. Also, being on your back allows your prostate to be massaged better by your partner's cock. This makes the penetration and thrusting feel better. Once you have some experience bottoming, then try it doggy style....completely different feeling.
Feeling your partner orgasm is a complete rush (for me at least). You will feel the warmth and wetness of his cum fill your rectum (unless he's wearing a condom) more than you will feel his cock pulsing.
Have fun and let us know how your first experience goes!

Of course, unless you have a long-time partner.....Do have your top partner wear a condom!
