Mohammad enjoyed touching Aisha during prayer

Volume 2, Book 22, Number 300:
Narrated Aisha:
I used to stretch my legs towards the Qibla of the Prophet while he was praying; whenever he prostrated he touched me, and I would withdraw my legs, and whenever he stood up, I would restretch my legs.

When prostrating, a person bends down on his knees, and stretches his arms out in front of them.

1) Why did Mohammad reach out to touch Aisha?
a) Was he trying to reach out and touch someone?
b) Or was he trying to touch his child bride, the one where he would get the divine inspiration from while he was making love to her? http://muslimhadith.blogspot.com/2008/04/mohammed-would-get-divine-inspiration.html

2) Why did Aisha feel the need to put her legs in front of Mohammad as he prayed?
a) Did the mother of all Muslims like to interrupt her husband?
b) Why couldnt she look for another place to stretch out her legs?
c) Was she seeking the prophet's love and affection?
d) Was she resorting to one of her tactics induced by jealousy of Mohammad's womanizing ways? http://muslimhadith.blogspot.com/2008/06/aisha-jealous-of-mohammed-womanizer.html

3) Why did Bukhari include this hadith?
a) Was it to provide an example for male Muslims to look to touch the legs of their wives while praying?
i) Is this consistent with Allah who promises 70 virgins in heaven for martyrs?
ii) As such, is Bukhari trying to hammer home the point that sexual touching during prayer is only fitting for Muslims?
b) Or was Bukhari providing an example for wives to stretch their legs out like the mother of all Muslims to bother their husbands during prostration?
