Why is there a lot of pressure down there?

I have a d*ildo that I masterba*te with sometimes andwhen I go passed a certain point it doesnt go any further and theres a lot of pressure, how come that is?

I'm not a girl and but I've used it once on one of my ex's with the same situation happening. I believe it has reached the cervix. Besides, why would you go so deep inside, most of the nerves are near the cl*toris/vagina region thou...

xxxmmgxxx is right. you probably just went to deep. this happens with a lot of girls, this has even happended to me. and if xxxmmgxxx was wondering, sometimes girls test this out to see if it gives more pleasure, or the dont mean to.
hope I helped :]
