Is there word like "excruciating" but relating to pleasure rather than pain?

I was hoping for some help on this one. I'm looking for a word that carries all the connotations of "excruciating" (intense, prolonged, unbearable, torturous, etc) but relating to pleasure rather than pain.

I could potentially use "excruciating pleasure", applying it's lesser used meaning to imply "extreme/intense" - it might even be somewhat poetic, but there's an implication of masochism that doesn't really fit my narrative.

Any suggestions? I'm happy to to accept a clever protologism if no such word exists!

As an example:

The slow, seemingly endless mingling of their bodies was _______.

Solution 1:

She experienced an exquisite pleasure.

exquisite adj.

...

4. Intense; keen: exquisite delight; suffered exquisite pain.

[AHD]

The 'unbearable' flavour perhaps comes from the collocation 'exquisite pain', but the word is also used to describe pleasure.

Solution 2:

Euphoric
adjective
characterized by or feeling intense excitement and happiness.

He felt euphoric pleasure.

Solution 3:

Ecstatic

1. of, relating to, or characterized by ecstasy or a state of sudden, intense, overpowering emotion: an ecstatic frenzy; ecstatic cheering for the winning team.
2. subject to or in a state of ecstasy; full of joy; rapturous: They are absolutely ecstatic about their new baby.

Solution 4:

Orgasmic (Google Dictionary)

1. relating to orgasm (of a person); able to achieve orgasm.

2. Informal: very enjoyable or exciting: The album is an orgasmic whirl of techno soundscapes

Solution 5:

A couple suggestions:

Bliss

or

Rapture
