SUSPENSORY LIGAMENT STRETCHING:

BTC (behind the cheeks) and downward stretches

Releases hidden internal length

Faster perceived gains but affects erection angle

More stretch sensation at the base

TUNICA ALBUGINEA STRETCHING:

Straight out, upward, and angled stretches

Targets the fibrous sheath surrounding erectile tissue

Slower potential gains but no erection angle concern

More stretch sensation along the shaft

Most experienced PE practitioners do both but periodize them — spending phases focused on one then the other. The tunica is a tough fibrous structure that adapts very slowly. The ligament is more responsive but has the erection angle trade-off.
