Pasanda. Please don't laugh at her not being able to 'find the hole'

I spent a lot of time at the beach as a youngster and when I got my periods at 13 wanted to use tampons so I could carry on doing so. My mum was against it for ages as 'girls' don't. (I think she thought once I put a tampon 'up there' a penis would just find its way up there too!
). Anyway, I just could NOT get one in despite trying everything various angles on the loo, foot on the bath, other foot on the bath, even lying down. I tried lube as well. I simply could not get one in. My mum made helpful suggestions (see above) and one day I was so stressed out I even asked her to do it. Thank fuck she declined as the residual trauma would have been to much to cope with 😁
I tried on & off and I guess eventually succeeded though I don't remember it.
I STILL STRUGGLE with them sometimes. I need my period to be heavy enough or it's too dry & I can't insert one. Sometimes I have more 'luck' lying on my side on the bed.
(Though I'm pleased to report it's not a problem with a penis 😁)
WRT swimming, for many years I'd happily swim with a tampon in, but I can't anymore as I'd either turn the pool/sea red or end up with pool/sea water up my fanjo. Neither of those options appeal!
My dates are no longer regular, but I think I'm going to try the tablets for my holiday later in the year (sea/pool parks).
