Is this normal?

Hello ladies. So i would normally google this question but its not coming up, google doesnt understand what im asking.

So ive been seeing this guy for a little over a month now, we meet up once a week and all that. Well ive noticed that now when i pee, the middle part (between the butthole and vagina) burns. At first i thought, “did we do anal?” Bc last week we took some ecstasy and i was like okay maybe he accidentally put it in the wrong hole idk. So i asked him did we do anal? And he said no. I was just like okay bc my butthole feels sore or something idk. Anyways, i went over again last night and we had sex sober. No anal, and when i woke up to pee i felt the same burning sensation. And i was like okay this is weird. And now im thinking, maybe its bc he does this thing where he grabs both cheeks and stretch them apart.

So for those of you ladies who have had that done to them, is it normal to feel a burn there from it? Thanks.
