I don't claim that lightly. First, consider the scientific fact that the anus is especially rich in nerve endings. Stimulating those nerve endings of your lover contributes to those pleasurable, orgasmic feelings during sex.
Next, The New Good Vibrations Guide To Sex writes that the anus also "engorges" the male sexual organ due to muscular tension and contraction. This means it provides incredible tightness for the male... something which most men crave for but can only dream about!
Scientific evidence aside, there is also the psychological element involved when a straight couple gets involved in anal play. The man is totally in control as he gets deep inside his lover FROM BEHIND... and the woman has to open herself fully and trust her partner is this intimate act!
With all these facts surrounding anal play, no wonder more couples are curious to try it! Anal Pleasure For Her.
