En los últimos 3 meses tengo un pequeño bulto duro en el eje del pene.

past 3 month i have a small hard lump on my penile shaft and i don’t have any other symptoms


If this lump causes any discomfort, pain, itching, swelling etc then you should consult a dermatologist/urologist.

Otherwise, no need to worry.

did you had any oral sex..???

no

I suggest you see a Urologist - you need to ensure that it cannot develop into something serious

any update?
