anal masterbation

My boyfriend is obsessed with anal sex and anal masturbation. Not only that he wants to do it to me, he also wants me to do it to him. I am trying to understand him but not knowing anything about this makes it harder to. Can you give me some details?

Anal masturbation is masturbation focusing on the anal area and common methods include the insertion of fingers or sex toys. Anal masturbation can be pleasurable for both men and women. The anus contains abundance of erotically pleasurable nerve endings and for men, anal masturbation can be especially pleasurable. The reason for this is that anal masturbation often stimulates the prostate, which also contains nerve endings. For women, insertion of an object during anal masturbation into the anus can indirectly stimulate the vagina. Muscles of the anus contract during orgasm. The presence of an object holding the sphincter open can strengthen the sensation of the contractions and intensify orgasm for both women and men. It is necessary to apply lubricant to the anal area before insertion of any object, because the anus does not produce natural lubrication like vagina. If you don’t like to do this, you need to talk to you boyfriend.

I decided to try anal masterbation the other night and when I put a finger up there, I felt maybe 2 hard sorta rough things towards the back side up about 3". I'm kinda worried. What could that possible be?

Hi. I found the same thing a few years ago and worried myself sick for two weeks before i plucked up the courage to go to the doctor.
How was i going to explain how i had found them? would he think i was a pervert?
I am glad i went, it turned out that it was a case of heameroids i never knew i had because i did not bleed or have pain. The veins inside your anus can swell and blood can remain there and solidify as mine had done. i was asssured they would disperse of their own accord, and they did.
However, i would urge you to visit your doctor and have it confirmed. You can never be to careful when it comes down to thinkg like this.
Good luck

That may just be your feces
