Doubts about urine drops

Assalamualaikum... I'm a patient of ocd... .i have a bad habit of
masturbation... a few days before i masturbated(i regret that) and then after
30 min i urinated and then went for bathing when i was bathing i had a
sensation and feeling in my private part that maybe i leaked a urine drops(i
have this sensation many times when bathing).I dont know really if i had
leaked a urine drop or not.Then after bathing when i had a towel wrapped in
my body i had a very strong feeling and sensation like feeling hot in and
around private part and don't know really if it is of urine drops or water
that is in my body.when i looked at the towel after that i see wetness as my
body is not dry...and I don't know what this wetness is of?because i didnot
dry my body after bathing. I don't know if that water was of body or of urine
drops because i had a very strong sensation.I don't know if it was waswas or
not..now I'm getting thought that everything in my house is impure.Because
maybe i actually leaked urine.But I'm not sure about that. I'm very depressed
about that.Is everything impure like towel etc.?
Note that i don't know if that wetness is of urine or body's water.
I'm getting a doubts that what if it is really urine drops.
I'm getting thoughts that because i masturbated...so these drops are my punishment from Allah because i sinned
because of that...i don't know what to do...
And what if the urine drops are actually leaked(i dont know about that)
Are everything impure? 
I know masturbation is a very bad habit...
But after this incident i masturbated and had a same feeling like pain and sensation in penis while bathing and after bathing...but don't if urine is discharge or not...or is it waswasa
Is my towel and everything impure?
Because i had use the same towel without washing...to clean my face etc..so everything like utencils furniture taps door etc is all that impure because of the doubt?
