i was 13 (gasp!) when i first tried, with a friend. he was very sweet, and came well prepared (yes was planned lol) BUT he wore a rubber, and well.... i am allergic. so everything dried up, and he couldnt get in properly. but the rest of it was good, and it went on for hours hahahaha
when i managed properly, i was 14, and i ended up being with him for 3 years, and we still talk occasionally. i bled every time, for first few months, only cause we were being 'responsible' and using rubbers, and i still didnt realise i was allergic, lol. we just used lube to combat me drying up, and i thought bleeding was normal, i had always been told it was to start with (just didnt realise they meant first time only! lol)
figured it out when we decided one day, to not worry about protection cause we didnt have any with us, and well, no dryness, no irritation, no bleeding, and sooo much more pleasant.
made the connection fully when next time i used protection, bad things happened again. havent used it since! lol
go on, bad girl i am!
