The most penetrating sex positions include:
1. Missionary Position: A traditional position where the male is on top, allowing for deeper penetration by adjusting the angle.
2. Doggy Style: The female is on all fours, and the male enters from behind, providing good depth.
3. SidebySide: Both partners lie on their sides, allowing for close contact and increased depth.
4. Sitting Position: The male sits on a chair while the female straddles him, allowing her to control depth and angle better.
