tittilating 

Arousing - generally with titties. Often used in erotic novels as a fancy way of saying 'A turn on'

"Last evening, my girlfriend did a striptease for me. It was really tittilating!"

"She slowly let him run his hand up her slender thighs and gradually let it lightly brush her vagina. It was the most tittilating experience for him."
