Does jelqing stretch the tunica?
The question in the title. Just curious because I’ve read some old posts about megaphallus and its application to PE.
Do you think the internal force generated by jelqing (forcing the blood and create pressure from the inside) can stretch the tunica? Like stretching exercises (external force) that lengthen the penis tunica.
Jelqing: Triaxial strain, stretching: axial strain?
