How Hamlet importuned Ophelia in her chamber?

To read this scene, four hands of Ophelia and Hamlet must be located. I analyze this adult content by word's logic, with no intention to make anyone uncomfortable.

OPHELIA:
He took me by the wrist, and held me hard;
Then goes he to the length of all his arm;
And with his other hand thus over his brow,^[1]
He falls to such perusal of my face,
As he would draw it. Long stayed he so,
At last, a little shaking of mine Arm:^[2]
And thrice his head thus waving up and down;^[3]
He raised a sigh, so piteous and profound,
That it did seem to shatter all his bulk,^[4]
And end his being.^[5]

[1] Three hands are fixed. Ophelia's one hand is not pictured yet.
[2] "mine Arm":: Ophelia's free hand. She shakes something a little with her arm (or she senses the shaking from what she is holding).
[3] "head thus waving up and down ... sigh":: the reaction of a man's orgasm. (head: penis head, or pate, or both.)
[4] "shatter all his bulk":: Hamlet's ejaculation. (bulk: load, alluding to semen.)
[5] "it did ... end his being":: a little shaking of Ophelia's arm did seem to die him, or exhaust him. To die is to reach orgasm (OED 1599).

In line two, Hamlet required "the length of all his arm" to let Ophelia's free hand work for him below. Arm has the usage as the narrower part of anything projecting from the main body (OED 6a, 1538, 1724). In line five, "draw it" is Hamlet's fantasy ("perusal") to paint Ophelia's face with semen.

Ophelia described this in an isolated sentence, "he comes before me." The author arranged an interruption to make it a pun -- Hamlet ejaculates in front of me.

OPHELIA: To speak of horrors: he comes before me.
POLONIUS: Mad for thy Love?

Ophelia was well dressed. She masturbated Hamlet but he can't get her pregnant in this way.

OED records come as to experience sexual orgasm in 1650 (OED v. 17), so maybe we can move ahead the date for vulgar usage. I can't find words for orgasm in OED before 1650, except die (1599 Much Ado).
