What the heck is this?

What the heck is this little orange speck? Ive been getting them, little by little lately- not a whole lot, just a couple on the TP after i wipe. My discharge has been clear like it is normally, so i honestly can't gauge if it's me having a UTI or something. I've been having issues with my bathroom habits lately too whereas I'll sit in the toilet for a while and still feel like I have to pee even though nothing is coming out. Also, depending on how much water i drink, it sometimes burns. I've been very dehydrated lately, so I'm assuming that that is a culprit cause.

So, to preface though, i had sex with my boyfriend a ton last week(9 or so times in the span of 4-5 days respectively) after having not had sex with anyone for something like 4-5 months. I am very tight (naturally, unaroused its honestly a struggle to fit anything bigger than my finger inside, aroused I can fit like two with some stretching, but i need lots of lubrication if I'm not wet enough), and he is, rather large, about 8 in length (the largest I've ever had) and the girth is enough that normal condoms squeeze him v tightly (looks vacuum sealed on him). Sex has been inconsistent; we both like it kind of rough, but he always starts off slow and gently so I can accommodate his size, and then we work our way up from there. Sometimes it feels really good, other times it hurts real bad and then there's times where it has the potential to to feel good, and it does, but there's just discomfort- this happened most often. Sometimes I can take his entire length with no problem, but others it hurts so bad because its like hes literally pounding my cervix, at this point we stop and switch positions. I felt like this info was needed, but what for specifically, I couldn't tell you. Just thought I'd include it.

But initially, after sex he'd always get me some water and then I'd go pee. A couple times i didn't; which is why I thought i had a UTI (and well the possibility is still there), because I had that "need to pee" sensation constantly, and sometimes it burned. And that's basically when this issue started. At first because of his size and scope i figured that it was just a bit of tearing and blood getting trapped in some discharge, but it's been a while since then and I still feel this way. We took a break from see bc of how i was feeling (and tbh we both were kinda exhausted) and thats when i figured that it was just irritation, bc I felt an ichiness only on the outside of my vaginal enterence. I felt like i was getting better and the feeling of ichiness + the bladder issues had gotten close to completely subsiding a couple days ago. Then i woke up this morning and it was back. Again, why I think it was an issue of dehydration.

I want to go to a Gyno and get this checked out, but i dont have insurance, or money to do so. I'm a broke college student and I honestly have no idea how I'd go about looking for and finding an OBGYN in my area. This is similar for finding an actual doctor becuae i have other health issues which I think are feeding into this. For reference I haven't been to the doctor for an actual check up in something like over a decade. I'm 18.

TL;DR: i dont know what is going on down there with these orange specks, and I have no idea why I have the urge to pee constantly either. This occured after i had a lot of sex with my boyfriend last week. My suspection is dehydration or a UTI, or both, but the only way to know for sure is if I go to a doctor and gyno- which isn't looking too rosy of an option rn.
