Whether you love it or hate it, you almost definitely have an opinion about oral sex, especially when it comes to performing oral sex. Sometimes you're into it, sometimes you're not, sometimes it's all about just focusing on trying not to gag if your partner has a penis, and sometimes you just give oral just so you can get some oral of your own in return. Like any other sex act out there, feelings on oral sex can often depend on your mood. Oral sex is complex. Oral isn't just about the physical sensations at play, but other factors too. For example, there is a complicated power dynamic and a vulnerability that are at work during oral sex.
