hi, im a 19 year old guy, and i am starting to get very very annoyed and frustrated by my premature ejaculation problem. Every time ive had sex, the most ive lasted is about a minute, sometimes less. i hate this because i always have to make excuses of some sort, and its embarrassing. even when i masturbate, i cant manage to last very long. please help me, this is affecting my self esteem.
