u r too young to be turned off to sex. sex is a beautiful part of our life and especially when you are enjoying it in love.
Foreplay is very important before sex. our bodies are not like machine to turn the button ON and OFF.
When u kiss, hug, and especially oral, it makes ur body sensitive and u start getting climax, talk to ur bf about cutting his nails, oral sex, different sex positions, sex toys, foreplay, intimacy etc etc.
we have a saying "Men needs a place women needs a reason".
Enjoy ur sex life and never ever keep things inside u. always communicate with ur partner. This is the key for success.
Good Luck
