My Period is five days late, no penetration

Hi, im 14 years old and I have hit puberty pretty hard. Im starting to get a lot of hair on my body. This sounds really weird but i was wondering if I should shave off that hair on my ass. It has gotten really bad and I need to know if it would be a good idea to get rid of it. Im not sure if I should tell my girlfriend about it either. Any advise would be greatly appreciated.

I was having sex with my girlfriend for the first time last night and after I came I pulled out and looked at the condom, it was dark so I couldnt really see if there was a rip so I felt it and it felt like a normal condom (slimmy from the lube), but the tip looked sort of deflated as if there was nothing inside it, ive been reading about condoms and what not and I think ive been storing them well and they are def not expired, and I think I left enough room at the tip, idk how much room it needs. Me and my girlfriend are extremely scared. Any advise is greatly appreciated.

Hello, I am 18 and in college. I have classes everyday at 8 so I have to be up at 730. I find it very difficult to get up each morning. I go to bed around 1 or 2 each night. After class I go back to my dorm at 11 and i usually pass out for 6 or 7 hours. I realize this is unhealthy but I'm so tired I don't know what to do about it. This has been going on for about a week and I took my temperature today and it read 96.6 three times. Should I go see someone or do something. Any advise will be greatly appreciated. Thank you.
