Anal for the first time...

TMI but I’ve been really gassy ever since, any one else experience this??

The LAST thing I thought was gonna happen when I went to my bf’s yesterday was that we’d have anal bc I was on my period too. But we were just hanging out and I usually get really horny on my period but it’s day 2 so my flow is heavy, otherwise we do it on my lighter days. But I just started playing with him and he was playing with my clit (fresh tampon in) and the he asked if I’d be ok with his finger in my bum bc sometimes we do that and we had just bought lube so I said ya I’d be down. Well we did that and he got to two finger and it felt kinda weird but also good. Then we went to put more lube on and there was a bubble or something when he was squeezing bc a bunch came out and I made a joke about how there’s probably enough just to put his dick in. Eventually I decided that I’d be down to try it, but told him not to get his hopes up for getting past the tip.... wellllll ladies, I got about 6.5 or 7 inches in probably.. (his dick is about 8-8.5 inches). And it felt really good. I was on top of him and told him he wasn’t allowed to move because I wanted full control.

Hahaha after it both of us looked at each other like wtf just happened and was that real or a dream.

How often (to those who have done anal) do it?
