A little discomfort down there🐱

I’ve recently had sex Saturday, haven’t had any sex for a few months. And I just went for it, you can say lol. I did it with someone I knew for a while now. It might be a little too much but his penis was thicker than what I am use to😭 (I know ladies TMI (For some) but I gotta tell it all so you can see what’s up)😂 & the length was🤦🏽‍♀️ my lord just crazy😂. Some said that you can feel discomfort due to the size of the partner or something like that lol not sure but I do feel a uncomfortable now. We used a condom but it was in towards the middle of sex so he wouldn’t release himself fast. It isn’t a burning feeling when I go to the bathroom but it’s like this tingly feeling, she itch sometimes, and I’m now having to change my panties as soon as I get home because the discharge just irritate my lady so bad. I know it can be signs of an STD but I’m really praying that it’s not🤦🏽‍♀️ I’m going to see a doctor tomorrow but I just wanted you guys opinion.
