Trying pegging for first time

Well my bf and i never tried pegging before, i first time knew what pegging is at all from the marvel comics movie Deadpool (2016) and we laughed it off and started as a joke. After 5 years of marriage and we are both quite the kinky couple i started looking for new things to experiment in bed with him when i actually found a porn video about pegging and i remembered the deadpool scene so i started searching about it and i loved what other ladies who tried it said about how it made them feel. That was i think like a year ago or year and a half ago and tbh i wanted to do the Deadpool scene lol, i mean celebrate womens day by pegging him, who watched the movie will understand the reference, for those who havent, in the movie the lady pegs her man for the first time to celebrate international womens day. So i brought up the subject for Dani more than a year ago and he was very refusing for it at first then i can tell he started slightly reconsidering but was still no until a month ago when i told him womens day is close and wanted to make it a special day for me as i peg him so he finally agreed as long as we stop if it hurts him physically (painful) or he hates how it feels, and gosh i would never want to hurt him, he is the love of my life and maybe one day the father of my kids. After he said yes i started looking into it when i found this blog and was very hesitant whether to register and share this or not but here we are. In case you were wondering Dani is a switch , he can be dominant or submissive, cause i dominated him before by tying him up, made him eat me, etc... So if its not too much to ask what are the things that you would suggest i do to him while pegging him that would make him enjoy it, note that i read all about putting so much lube, being verbal and constantly asking how it felt, etc.... what i am asking is how can i dominate him, like make him feel dominated and in a sexual roleplay way helpless and feel he powerful controlling feeling that other ladies felt while still making him really want it more and ask for more after. Sorry btw for the long text, got carried away lol.
