Mohammad had lots of semen on his clothes

Volume 1, Book 4, Number 229:

Narrated 'Aisha:

I used to wash the traces of Janaba (semen) from the clothes of the Prophet and he used to go for prayers while traces of water were still on it (water spots were still visible).

Volume 1, Book 4, Number 230:

Narrated 'Aisha:

as above (229).

Volume 1, Book 4, Number 231:

Narrated Sulaiman bin Yasar:

I asked 'Aisha about the clothes soiled with semen. She replied, "I used to wash it off the clothes of Allah's Apostle and he would go for the prayer while water spots were still visible. "

Volume 1, Book 4, Number 232:

Narrated 'Amr bin Maimun:

I heard Sulaiman bin Yasar talking about the clothes soiled with semen. He said that 'Aisha had said, "I used to wash it off the clothes of Allah's Apostle and he would go for the prayers while water spots were still visible on them.

Volume 1, Book 4, Number 233:

Narrated 'Aisha:

I used to wash the semen off the clothes of the Prophet and even then I used to notice one or more spots on them.

Wow... Mohammad was quite the man. I am sure Bukhari included these verses because of his admiration and total respect for Mohammad.

Yet, once again, this story brings to mind several questions regarding the life and times of Mohammad.

1) If Mohammad had many wives, why was his semen on his clothes?

a) Did Mohammad withdraw and get the semen on himself?

b) Couldn't Mohammad have shot the semen somewhere else?

c) Was Mohammad the inventor of the "money shot" which resulted in his poor aim?

d) What type of sexual moves was Mohammad pioneering where Aisha was just never able to clean all the semen stains of his cloak?

2) Why didn't Mohammad use another cloak before he went to preach?

a) As a prophet who was entitled to 20% of the war booty, couldnt he have at least obtained another cloak/robe just for that reason?

b) Couldn't Mohammad have waited until the wet spots used to clean his semen were dry before he went to preach?

3) How much semen did Mohammad have on his cloak, seeing how Aisha would always find another spot?

4) Was it customary for people in 600 AD Arabia to have semen on their clothing, especially considering that Aisha made it a point to relate this story to several people, as if she were complaining about having to clean Mohammad's semen stains?

And finally, a question for modern day Muslims:

If Mohammad is the perfect human being, and should be imitated by all Muslims, shouldn't all Muslims make sure to have semen stains on their clothing, and then have their wives clean it with water before they go and work, in order to faithfully imitate their prophet?
