Great piece, Holly! I wrote something more towards the shaming aspect of being pegged, since folks like to sex shame!
It took my husband a long time to admit he enjoyed anything anal related (on him). And every bit of that was due to being afraid of being shamed. I'm so glad we've been able to work past that.
As for double ended dildos...those things are really the devil, unless you use them with a harness. The insertable end for the giver feels great, but no matter how strong your kegel muscles are, the anus is stronger. It's anxiety inducing trying to hold it in, while pegging. (It's a little easier when using it with another woman)
Using one with a harness removes the stress of worrying about it falling out.
Just my two cents <3
