If your glans are wrinkled, then try this simple method.
1. Make slight O-grip with thumb and index fingers. Around base or middle is fine. Hold for few minutes and see difference.
2. Or make slight jelqs and check difference.
Outflow of glans blood lays in outer veins. If you see huge difference then reason should be there. Then compare with overall EQ. 10/10 erection makes shaft rigid as steel. You can’t push even a little bit, and you can’t bend either. It’s basically like rock and even rotation is painful. I’m not sure if it’s possible to have 10/10 erection and wrinkled glans. And speaking honestly I don’t know much what to advise besides kegels.
