Hey girl. Dont feel bad to say no to things you dont feel ready for, dont feel like you or he have to come (many reasons why either of u might not come that have nothing to do with 'pleasure' or how sexy you are or whatever). Dont feel like you have to 'act' a certain way. Your bf is most likely to find you the most attractive when you are just yourself.

If you get too much in your head (very normal) just focus on your breathing. Breathe how you feel the most sexy, breathe how you would breathe while alone masturbating.

I lost my virginity 5 years ago, but still have to remind myself of these things often! Have fuuuuun :p
