Boa shedding question

[dinosaurdammit]

So my male has shed 3 times in the span of a month, he seems to be in a constant shed for 2 months now. Is this normal? Food hasnt changed, temps are the same, humidity is now at 75 precent because hes in constant shed. Is it normal if its not what do I do to stop it? Has anyone else had this happen? I dont want to bother him much while hes molting but i feel so bad because he always gets a foul attitude.
