This is a single heterosexual man we're talking about here, with a hardon and a clear and present opportunity to get laid. If there is a problem with contact lenses in such a situation, the only appropriate action is to entirely remove them, throw them away, and proceed with the rest of the evening in a state of mild blindness.

Scared seems the most likely explanation. Not necessarily over the top, but it could be that the guy is not used to this kind of sudden opportunity and was not entirely adjusted for it, or expected things to move more slowly and got freaked out. It could be that there is some additional condition involved, something that made the scene embarrassing for him. Maybe he got laughed at for his 3" unit during his last one-night stand and he was thinking there would be more romance before tickling. Maybe he's a relapsed Catholic and this brought up some guilt issue. Maybe you said something that reminded him of his dead gramma.

Maybe he thought that the over-the-topness gave him license to act weird and not typically respectfully. Like, she's so adult, she understands that guys are gonna weird out from time to time and just escape with whatever explanation occurs to them.
