I did want to say that if it hurts, something is wrong
. DO NOT accept pain as part of anal sex!
Proper warm up, which for many women includes having at least an orgasm or more first, good lubrication and complete relaxation is necessary!
You can do damage to the anus by having painful anal sex. If it hurt... you're doing it wrong.
There is a great book by Tristain Taoromino which you can buy on THIS website called The Ultimate Guide to Anal Sex for Women
is a must have.
You need to take your time, be relaxed, have an orgasm, warm up and even train. It took my husband and I more than a month of anal training and play before we could have full penis-anal sex. It was worth every minute of the training and work. Any guy who just wants to "stick it in" without first making sure you have an orgasm and are warmed up, lubed up and WANT the anal sex needs to be eliminated from your life. That's no way to LOVE someone.
The road to pleasurable anal sex is a lot of work, for both receiver and penetrator. If your partner isn't willing to do the work to help you come first and take his time, he isn't worth YOUR time.
