The emotional part is honestly subjective, although pretty important. Its more about your mindset at the time, so have some experiences:
While sorta high and talking with bf it was like a warm feeling of comfort and love that made me feel really touchy and sensitive. Gave me the most intense experience so far, basically just an overwhelming urge to keep that loving feeling and start bonding.
Usually whenever I'm alone doing it I just get generally worked up over fantasizing and focus on the sensations which lead to a lot of more perverted thoughts and feelings. This kinda varies most on how emotionally vulnerable you are at the time, again while a bit high it felt best with this complete focus on the physical sensation and my mind going blank aside from a sort of feedback loop of 'Holy fuck this feels amazing' actually making it feel better. Though oddly if you concentrate too much on trying to feel it specifically it won't feel good, you need to let yourself go and just get taken for the ride and enjoy the act itself, not what its doing to you. Sounds weird but basically its like trying to tickle yourself, can't force it on yourself. Let the toy do the work, don't think too much.
When you're actually doing it with someone its again just an incredible feeling of warm love, however a lot of it comes from how your partner is acting. Unfortunately my bf has a bit of a stone face during sex so while I still enjoy it and am compelled to cuddle during/after it this isn't as strong as fantasizing about him while actually talking too.

Fucked if I know for sure, but I'd bet its because humans fuck even more than bonobos. See above, a good dicking makes you a lot more likely to pay nice with someone than try to fight them. So guys who got dominated and enjoyed it probably stuck around in a tribe they wandered into more often and eventually bred.
