I wouldn't put anything on it as to me it looks like you have found his nipple and the black mark is just skin tone (skin tone matches hair colour)
Maybe you're right, I asked the same questions on reddit and two comments said the exact same answers like you.
TBH, I didn't know their nipples are that near their back legs... I guess I learned something new today.
