PE Lig Stretching - > Erection Angle

So I read some stuff on loss of tugback but I didnt really understand it. Then I read some more on erection angles and I was wondering how PE affects the angle? I got a nice upward angle now but I mean lets say I gain an inch. What will change? Or even more than an inch. I mean will I have negatives for having sex or certain positions?? Anyone can give me a quick rundown on those subjects?

What is tugback? I have a super high erection angle, and I’m actually not a fan of it. For one reason: My wife likes it when I mount her face and stick my cock in her mouth, but it’s difficult with that angle. I wouldn’t mind having my ligaments loosened.
