my partner has had a massive breakdown, this writing resonates xx

to an extent i agree with Jimmmy with regards to relaxation being key.
''The biggest barrier to this kind of play is mental, not physical. Achieving total relaxation requires you to be in the right place in your head.''

however i feel he went a bit off track with anal, given Read more… the OP specifically says vaginal in her opening post.
i don't think a vagina can be ''trained''
as said in a previous comment, for myself, a vagina owner with 25 years fisting experience,
sometimes the tiniest hand isn't going anywhere, other times 2 is awesome
i don't need a nappy either

i believe they are (jokingly??) saying that fisting was and/or should still be?? an activity exclusively for gays? in substitution for penis fucking, because gays have always fisted and fisted first???

yuvutu has some more sensual fisting content

a few more tips
whilst it IS important for the person being fisted to be comfortable, imo it is MORE important that the person DOING the fisting is comfortable.
the fister should accept that they could be wrist deep for some time
i usually suggest the fister either sit with their back against a Read more… wall, or in a sturdy dining style chair with the fistee at the foot end of the bed.
whilst hand size and nail care are important, mind set of the fistee WILL affect the process more than hand size.
some days even a tiny hand will go no where, other days your hand will almost feel swallowed
remember, a tiny movement is huge inside someone so the last thing you need it to be crampy or twitchy
so choose yaself a comfy spot :)
