ANSWER:

1. No problem. However, deliberately touching the private part invalidates wudhu and one should repeat it.

2. When you take ghusl for major impurity your wudu is already included in that and there is no need for another wudu.

after intercourse with my wife..I do ghusl as per sunnah procedure and then start washing my whole body with shampoo and soap..in which I touch my private for cleaning with soap..my questions are 1) Is it permissible to combine ghusl and then bath with soap 2) if I want to pray after ghusl, bath do I need to do wudu again as I have done it while doing ghusl???
