How would Spenser's treatment of human sexuality in Amoretti compare to that in Epithalamion?

There are many significant differences between Spenser's
Amoretti sonnets and his celebratory wedding
Epithalamion. Aside from the style and structure of the two, the
Amoretti chronicled the passage of real events in real time, i.e.,
Spenser's courtship of Elizabeth, while the Epithalamion celebrates
the real event of their wedding day and night.

Since the two tell of
two vastly different [then] experiences, that of courtship and marriage, the topic of
sexuality is foreign to one and natural to the other. As a consequence, the treatment of
sexuality in Amoretti is veiled and subtle while in
Epithalamion it is gently overt.

An example from
the Amoretti sonnets is in Sonnet 5 in which, in veiled terms,
Spenser speaks of looking at Elizabeth with lust as indicated by Threatening
rash eyes:

Threatening rash eyes which gaze on her so
wide,
That loosely they ne dare to look upon
her.

An example from
Epithalamion is in the 18th stanza (also called 18th poem). The
wedding is ended, and Spenser and his bride have the night ahead of them. Though there
could be no occasion to speak of marital intimacy in his courtship sonnets, Spenser is
now free to speak of it and does so in a metaphor of what awaits them under the cover of
night sable mantle:

me,
that no man may vs see,
And in thy sable mantle vs enwrap,
