Don’t thrust too hard, especially not at first. His mouth and throat will probably take a while to get used to your cock so start gently and respond to the way he reacts to you. If you’re both comfortable you can enjoy the experience for longer.
Most men are going to prefer to suck a cock that’s clean and smells good. Wash carefully, particularly if you have a foreskin.
Having someone suck on your cock carries no real risk of you catching HIV, but it is possible to pick up other infections, such as gonorrhoea or syphilis. Wearing a condom when you get your cock sucked can prevent most of these risks. However, as most men choose not to do this, regular sexual health check-ups will make sure you know about any STIs you may have picked up.
