Remember what is a yum for some folks is a yuck for others. This is how it is for Anal Sex.
Anal sex or anal intercourse is generally the insertion and thrusting of the erect penis into a person's anus, or anus and rectum, for sexual pleasure. Other forms of anal sex include fingering, the use of sex toys for anal penetration, oral sex performed on the anus, and pegging. Wikipedia
Lube and relax, anal sex can be very enjoyable when done correctly. I highly recommend getting a tube of Anal Ese Cream Desensitizing Lube to make it more pleasurable. Or some similiar Lube and relax. (Anal Ese is a desensitizing formula that heightens the satisfaction of backdoor play. Benzocaine, the active ingredient, is a local anesthetic that reduces pain by relaxing the nerves surrounding your tight hole. Apply generously to your sensitive area to relieve the discomfort of anal penetration. Anal Ese is cherry flavored for tasting rimmings and will give you the confidence to explore painless anal sex.)
Please use a condom for hygenic reasons.
