Tight suspenspry ligament - surgery

So I'm writing here a question about a tight suspensory ligament. Since always I've had a very upright erection angle (like in the picture i drew, excuse my art skills) which made most sex positions quite uncomfortable. If I bend my penis to 90 degrees in relation to my body it feels like it's gonna snap. Recently I've seen an andrologist who suggested me surgery ( ligamentolysis ) to lenghten the suspensory ligament to make my erection angle more flexible. Does anyone here know if I can work on it through manual exercises? Or is it worth it to go through with the surgery?

BTW: excuse my english - it's my second language.
