ADVICE PLEASE

Aileen • Aquarius ♒️▪️Taken❤️ 11-04-14▪️ I'm trying to discover myself , keep pushing and fulfill my plans😏😌
I've only had sex with one guy. Idk how things really work and I cum really quickly, is that normal? I'm very aroused but I hear women take longer yet I cum fast. And I don't have this build up , it just feels good through out the entire time. How can I control it? 
Literally I need advice haha does this happen to you girls?
