Help me I can't stop masturbating with my underwear and it hurts like shit is there any alternatives to this?
Stop masturbating until you're no longer sore. Sounds difficult, but trust me it's worth it. Then fap only with lube in the future (shower, lotion, ect.). Personally I just gently rub the head while rubbing the shaft, if I lack lube. Maybe rub some soft tissues paper on it. Baby wipes feel similar to a blowjob with less suction. To name a few. Always be gentle when you're dry, no exceptions. Best of luck in future fapping.
Change hand....
get better quality underwear
