Well first i wanna know how old you are because i was talking to a friend last night and she said she had sex for 5-10 mins and she didnt even orgasm cause she was 14. I have no idea about you girls but i know you can start off slow and start kissing her. kiss her neck and nibble her throat and all that good stuff. next you can try to finger her but if she refuses, stop. next u can try to kiss her belly and try to go down on her, but if she doesnt want it, i dont know how u can make her orgasm.
