Treasure Seeker’s Elegant Jewel She’s 11 weeks today.

Hello everybody. My puppy is 9months old now, and he started having this problem with the beginning of summer, in winter it had happened once but the bumps were gone after a few days. Now I have no photos that show the problem well, but only a recent one in which it has 3 or 4 bumps... tomorrow...

My dobe is 2.5 years old unfixed male. He has recently been humping me at almost every opportunity. I have read it is not always a sexual thing. I tried deferring with a toy and snack. I also tried time outs in his kennel. Longer exercise sessions to tire him out. Nothing is working. Anyone...
