Enjoying simultaneous oral sex is something you should try at least once in your life. Let's not lie, for it to be comfortable and enjoyable it takes some practice and skill. There are dedicated fans and detractors who prefer "you first, then me," but either way, before giving your opinion, you need to try it.
The 69
Not only humans, but also spiders with their eight legs are happy to practice 69. It is undoubtedly the most democratic and egalitarian position between the sexes; the only flaw is that it has become so idealized and expectations are so high that the results are not always convincing. Keep in mind that doing 69 doesn't mean both partners will reach climax at the same time; each has their own timing.
Disadvantages? Getting carried away by pleasurable sensations while working hard to stay focused on stimulating the other person, and the logistical problems caused by differences in the size and weight of the participants. Advantages? If you can work together, the experience will be fantastic.
As you can see, the menu is extensive, which dish would you choose for your last meal?
