Nooooo thank youuuu! Some toys like the bendable rose P.O.S. are 100% impossible to get inside me. My female parts Dr. said that one of the reasons I was having such severe pain during intercourse (even after I had surgery for the endometriosis) was due to my being so small. He said everything was so close together in there and it causes pain during entrance which does get better when we make sure I'm super horny first and it also plays a role in the pain I feel in my lower areas similar to contractions (endometriosis things.) I thought something was wrong with me for not being able to use dildos and toys that are even medium size, but I learned to just be thankful and love my smallness & not get upset when toys are a bust because they won't fit. Anyways, my point is, some toys average sized, will be touching the bones around my hole & to insert a toy that large would result in ripping my hole! I just gave up on anything that big after a tearing it. I still get tears from my partner even when I'm super lubed! It heals quickly, but hurts. So Hell no I'd never try fisting.
I've never had anything in my booty and certainly don't want to slap a fist in there! Sounds far too dangerous and ugh, just not our thing. Neither my partner or myself are the least bit turned on or interested in the idea, but we know a couple who are able to fist! I so thought they were lying until I learned it was possible. I just could'nt believe a vagina could actually stretch enough to have a fist going inside. I mean, child birth I get. I was shocked when I learned it was real!
