Knowing that it's kind of taboo in a way makes it a huge turn on. Then it kinda stops hurting when you finally relax, but for me, it can get bad again when he starts thrusting. True story — the man who is now my husband and I went there on the very first night, but that is highly unusual for me! For me, it's something that only lasts five minutes.
I usually use a vibrator on my clitoris along with anal penetration, but not always.
