Ghusal

Taking long to make ghusal

Q: I get frequent wet dreams. The problem is that it takes me about 30 mins daily to do ghusl. The main problem in ghusl is washing my feet which can take upto 20 mins because my feet has dirt inside the lines so I rub them with a pedicure stone until they are gone.

I am moving to a hostel for educational purposes and there I will have only few, maximum 5 mins for a bath as there will be a communal bathroom. Plus, the temperature can be 0°c or below too so I can't take a long bath. What do I do as I am becoming depressed due to this thing?

Ghusal becoming compulsory if mani comes out without any desire

Q: Because of my excessive masturbation, I got pre-ejaculation. If I see a girl continuously for some seconds mani comes gushing with desire automatically without even touching my private part and without me wanting mani to ejaculate. Is this because of my sickness? Most probably this is a sickness because when I defecate with force, then without desire mani comes out.

My question is:

Many times I see a girl and feel desire in my penis and I feel something is going to come out gushingly so what I do is, without holding or touching my penis I pinch myself on my legs or I think about something else so that the desire goes away and then after sometime mani comes out without any desire and also this comes without wanting to do it. Must I do ghusl for this?
