Touching a Utensil Before Taking One's Fardh Ghusal

Q: After a wet dream or sexual relation with the wife when ghusal becomes farz, if I touch any utensil like a glass or plate would it become najis? Or I just washed my face then wiped it on a towel then I used this towel after I have a shower, would my ghusal be valid? Or do I have to wash these before I or someone else uses it. I get confused thinking this is wrong that until I have a shower I should not touch anything with wet hands.

Urge to Break Wind in Salaah

Q: I was performing salaah and during my last sajdah I felt accumulated wind about to come out i.e. I had the urge to break wind, when I sat back from sajdah that feeling was gone. Now I don't know whether the accumulated wind came out without me noticing it, or that the accumulated wind just disappeared into my body. In such case is my wudhu nullified? Can the feeling of accumulated wind just disappear (without coming out) back into the body? Or must I regard it as having come out even if I did not feel something coming out? Should I repeat the prayer and the prayer I have prayed after it?
