Then there’s this: (no angel sex)

The angels view also assumes that angels can have sexual relations with female humans. Bruce Waltke points out, however, “This interpretation…contradicts Jesus’ statement that angels do not marry (Matt. 22:30; Mark 12:25). It is one thing for angels to eat and drink (see Gen. 19:1–3), but quite another to marry and reproduce.” Some interpreters respond that Jesus was referring only to the marriage contract and not to the marriage bed, but this makes Jesus’ statement nonsensical in its own context. Jesus was responding to the question about having a marital relation resulting in children, and He clearly denied that heavenly angels can have sexual relations.
So you conclude from Jesus’s statement that angels in heaven do not marry that fallen angels cannot have sex?
No he wasn't. The question put to Jesus was about multiple brothers marrying the same woman (because brothers assumed responsibility after the death of brothers). The question was straightforward..."Whose wife is she?"
It is not about sex.
There was no mention of or implication about sex.
