Factors that break ghusal

Q: How many days my body will be "napak" if I smoke cigarettes?

Q: After urinating, when rinsing the private area with a hand shower, the pressure of the water is satisfying. Sometimes, I get really aroused, which follows a discharge. Is this counted as masturbation? Do I have to perform ghusl? 

Q: I want to ask a question about husband and wife relationship. If they perform romance, do touching with hands on each others parts, just touch ones parts to the others part, then before next prayer is it necessary to take a shower to be clean or shower is not compulsory?

Q: I had the bad habit of masturbation. After doing this act I never walked 40 steps or urinated. A clear liquid came out, is ghusal nessacary?

Q: If a male awakens to find he has discharged semen during the night, but without known arousal or a dream, does it neccesitate ghusl?

Q: I'm getting married tomorrow and I wanted to use the patch as a form of birth control. I'm worried that my ghusl wouldn't be accepted if I do so I started taking yaz. It already started affecting my haidh and I'm scared of the side effects. Is ghusl valid when using the patch?

Q: If man's private part did not fully enter a woman's vagina and the woman doesn't release mani but the man's sperm flushed out, so in that situation does ghusl become waajib on the woman?

Q: Do I need to take a bath if someone smokes weed in front of me?

Q: I woke up after having a wet dream. I immediately made Ghusl and then remained awake for sometime during which I performed Salaat. I then urinated. A sticky, semen-like fluid came out with the urine. The urine was also very cloudy indicting the possible presence of semen therein. I therefore made Ghusl again.

1. Was it necessary for me to make Ghusl again after observing this about the urine?

2. Was the Salaat valid?

Q:

1. When a man inserts his tip of penis in other man's anus, both should have fard ghusl right?

2. Is the ghusl fard even if when both had worn clothes? E.g. If one had worn pants and the other had also worn pants but penis went inside anus along with both pants. Is ghusl fard still?
