Anal masterbation...what happened?

Okay so I am a straight male and I figured I would try some anal masturbation. Started with the fingers and liked it. Than I tried a condom on a toilet plunger and damn I loved it. Went up and down on the plunger for so long that it was hot after I got finished. So next I went and ordered the Rebellious Ryan 9 Inch Dildo. Well it is huge, but I got part of it in and well the sensation was not as good. Why?

I am guessing I was not opened up enough to enjoy it. In other words I was not able to go up and down on up like I was with the plunger.

 

i assume the plunger sucked your intestines out your asshole, and now you can't feel anything because you're actually dead.

 

Wait, what?
That seems a bit harsh..

 

Ok Eric, if you feel the need for a bigger dildo, I'm not positive you are all that straight at this point.

And yes, you need to prepare more for bigger objects. You also need lube.

 

Patience is the key. I have had sessions that lasted and hour and a half.
