Do guys feel pressure to ask a girl that they like out?

Especially shy guys, but guys in general. Do they feel pressure to ask the girl out that they like? If they do does that help give them the courage to go ahead and do it? Are they likely to wait a long time like until the last possible moment before they ask her out? Also if their friends know will they keep pushing him to ask her out?
