Lump under skin of Penis

Patient: Hello,I’m fourteen and I have a important question.To be honest I like to masturbate alot and well I noticed that there is like a little spot or lump or the skin of penis.I have had it for about 2 months now but it doesn’t bother me.It doesn’t hurt but today I was looking at it and I noticed there was a bit of white stuff coming out of the top.It might just be a spot but I really want to be sure.No one else knows about this.If it is a spot what do I do?Do it let it just go away or do I consult a doctor?Thanks for your patience and I hope to get a reply 🙂
