Judging by some of the terminology you've used, I was wondering if maybe you're a retired Starship captain or possibly had a naval career.
If it's the latter, may I suggest you could rig up a bosun's chair.🤔
Other than that, I guess there's probably a geometrical formula ..... something to do with the heat of the meat v the angle of the dangle.
As a fellow punting veteran, may I recommend one of my favourite positions, which although it somewhat curtails your thrusts, it's very comfortable, the lady does the work, you can still achieve deep penetration, you still get a great view of the heaving bosoms, kissing is available and there's a fair chance of the lady achieving orgasm should she so desire.
