Read the excerpt below and answer the question.

You sea! I resign myself to you also-I guess what you mean,
I behold from the beach your crooked inviting fingers,
I believe you refuse to go back without feeling of me,
We must have a turn together, I undress, hurry me out of
sight of the land,
Cushion me soft, rock me in billowy drowse,
Dash me with amorous wet, I can repay you.
