Weaker erection when legs apart

I am experiencing weaker erection to a point of completele loss of the erection when I put my legs apart. I can experience this when sleeping in a sideway position and having hard morning wood. When I then turn to the supine position and spread my legs apart the morningwood gets suddendly weaker to the point of complete loss.

When being aroused I also experience a weaker erection when opening my legs but it isn’t as bad as when having morning wood.

Is this something normal other experience too or does this indicate a venous leak?

Maybe doing kegels (Pelvic floor exercises) can help with this? My theory is that maybe this muscle is too weak and pressing the legs together expands it resulting in a harder erection.
