Ghusal

Ghusal for a man who inserts his private part into another man

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 the penis went inside the anus along with both pants. Is ghusl still fard?

3. Is the fard ghusl same as ghusl janabah?

Fluid coming out after ghusal

Q: I broke my ghusl yesterday and today before performing ghusl, I trimmed my pubic hair by applying shaving gel then fluid started coming out of my private part. I sat on the toilet seat for like 20 minutes squishing my private part to get all the fluid out, but it was continuously coming out. I got under the shower for 5 minutes and again went to the toilet seat to check if it was still coming out, there was a little of it but after squishing it twice, the fluid stopped coming out, I checked twice and there wasn't any fluid. I performed ghusl but I am not sure if that fluid came out during the performance of ghsul or not or afterwards. Do I need to perform ghusl again?

Note: I face a lot of waswasa during ghusl and it takes me about half and hour to perform ghusl! It's really hard for me so I just don't want to do it again!

Washing the feet for the second time after having a shower

Q: Whenever I have a shower and after I wash my feet and step out to dry myself and dress myself then when I go back to wipe the base of the shower cubicle where you stand, I find there are small hairs and little fluff. Does this mean I have to wash my feet again and the areas I've stepped on? Or are these hairs pure and I can just ignore it?
