Raw sex/ sex in general ruins lives?

Okay so I recently started having sex with my 1st love and idk if it’s the condoms or the fact that I slide his dick in every so often raw for like 10 secs... but I haven’t felt the same... I feel like something’s off. I feel itchy as hell right now in my nether regions, granted, I’m very sensitive to every damn thing and I recently trimmed which was a mistake IMO. Are the rumors true, do penises really throw off your ph? What should I do to treat the itchiness? I can be a masochist at times so I’m two seconds away from dousing my poor miss with hot water. Also, I had sex some days after my period still within the fertile window and I put his raw dick in me just for the experience. He didn’t ejaculate but should I be worried? Lastly, I feel Like my insides have been shifted around after having sex, its uncomfortable sometimes since Ive know what it feels like to have an unbothered vagina for yearsssss. I’m starting to wonder if it’s all worth it 😣 All comments welcome! I need answers fassssttt!!
