If you’re asking me the question, ‘Am I too young,’ it’s because you, yourself, had the feeling that you’re too young. When the question doesn’t come to your mind any more, then you know that you feel old enough.Keep in mind that giving oral sex isn’t a safe practice, which means that you will need to have your partner wear a condom. As for technique, the underside of the head of the penis is where men have the most sensation. So you will want to focus on stimulating that part of the penis.Since each man is built differently, there are no hard and fast rules (no pun intended). You will need to find your way with each partner, asking for feedback and paying attention to his response. You will be fine.
