Me & my bf had sex for the first time 2 days ago. he's well endowed and it wasn't his first time but it was mine. i am still bleeding is this normal?

May be: How much are you bleeding? Could you be having a normal period? Spotting due to tearing of hymen could result in spotting for a couple of days. If it is more than spotting and lasts more than 3-4 days, it would be prudent to see your doctor. If you do not wish to be pregnant, use contraception all the time, every time. You may consider implanted contraceptive, or IUD. Practice safe sex. Get HPV vaccine.
