Why does it take me so long to cum when I finger myself or when some guy does it?
Are you comfortable masturbating?
Are you comfortable with your boy friend?
Are you embarassed by it?
Do you know what you like and how you liked to be touched?
its probly by how you do it.. or if your conforitble.. but it should take about 10 minits. for me it does with my boyfriend but itz natural if it takes more
