NSFW Burp while pooping and now can self lubricate after getting violently ill

I 23F got very sick with a virus that passed through my family a few months ago that involved a full night of throwing up every 30 minutes or so and eventually not being able to hold my diarrhea in while throwing up. This was really straining on my body since I was doing this in 30 minute intervals for hours on end. Since then, I’ve noticed two major changes with my body, and I am wondering if they are indicative of something wrong health-wise either from before I was sick or after being sick.

The first thing is that now when I push to poop, I burp, and when I burp, if I have a bullet in the chamber or I am sick with diarrhea, it gets quite close to pooping on the spot (quite here is relative to how much in control I was before - I haven’t had any accidents. I feel like if I had a coughing fit, which I haven’t had yet, it could be just enough to make me go without wanting to). I had never experienced this prior to being sick. When I look online, all I saw were quoras and an article which explain why the two can be connected, but I haven’t seen anything about why this would start to happen and not go away after intense straining/ being sick.

The other thing that has started to happen is my ability to self lubricate during sex. Before being sick, I could only self lubricate after orgasming, with zero exceptions. I thought it was a purely genetic thing since my mom had implied to me that she suffers from being dry as well. I’d gone often to the GYNO asking about this and they’d always tell me that I “just haven’t found the one.” Now, this does coincide with having a new partner (my only one since being sick), but now I produce so much lubrication in a very short amount of time of penetration that it leaves puddles and I can now feel my vaginal walls much more relaxed when this happens. This is mainly a very welcomed change for me, though I worry about if I am more relaxed than I should be - is it relaxing or weakness? - also because my boyfriend did tell me he can’t feel my walls nearly as much after I become relaxed (I asked him).

A third smaller thing is that I notice a delay now of around half a second between my trying to stop the flow of pee and it effectively stopping. This sounds weird but I’ve always found fun to sometimes try to recreate a song while peeing by trying to align peeing with the beat of the music. For this I notice the delay since I’ve beat boxed so many times before.

I think it may be relevant to mention that I had unknowingly did pelvic floor exercises all my life which led me to have an incredibly strong pelvic floor before being sick, maybe even too strong. I know much stronger than the average, since anyone I told about my beat boxing pee would be so surprised, and because I was able to push an ex boyfriend out with just contracting my vagina.

I guess in my head I wonder if I had built a too strong pelvic floor that was actually holding me back from naturally relaxing during sex but now is weakened, leading somehow to burping and pooping becoming intertwined and a short time delay in beatboxing. Or if all that straining did something to my nerves down there which is why not only do I relax but I send a flood out - I really don’t know. I would appreciate if anyone would know if what I shared is indicative of something being unhealthy, either before or after getting sick. I don’t take any supplements besides a multivitamin fizzy tablet for water and I’m on adderall. Thank you to anyone who reads this or comments - I greatly appreciate it.
