23M. Is this balding? Or just the way my hairline is? Please advice.

Ultra sensitive to Finasteride. Took 0.25mg for three weeks now and everytime I take it I get desensitized dick, saggy balls and weak erection.

What should I do? I wanna keep my hair until 35.

Thinking about getting a transplant when I turn 25 and have enough money.
