The answer is…*drum roll* the 69 standing position.

Don’t worry if this one never even came on to your radar, as one member of the stylist.co.uk team pointed out “you’d have to be going with The Rock to try this one.”

For those who aren’t familiar, this is your classic 69 position in which both sexual partners perform oral sex on each other simultaneously, but in this version, one person stands upright, holding the other off the ground and close to their body with both arms wrapped around their waist. Sounds pretty tricky.

56.8% of women surveyed felt this is the most nerve-wracking position they could try, closely followed by 42.7% of men.

Participants found that anal sex was the second most difficult position to do, with 54.6% of women saying that they would find trying this uncomfortable. Although men felt less concerned by this position than women, 30.5% still considered it a difficult one to pull off.

In third place was another particularly athletic position: 24.8% of women would pass on the kneeling wheelbarrow, and 18.6% of men agreed. If you’re struggling to picture this in your head, the premise is for person one to place both hands on the floor while person two stands behind them. Person one wraps their legs around person two’s waist, who holds their hips for support. Let’s just say if you want to try this one, you might need some core strength.
