Yes, but people go funny in the head too if sexually frustrated (also religiously frustrated, but more people are susceptible to the former). You could have anonymous wordless one-night-stands to get some of the benefits of partnered sex without it influencing the rest of your life, but you still get frustration from sexual tension between specific people.

Alternately we could take a leaf from bonobos and replace "hello" and "thanks" with sex. If everyone is permanently hovering between afterglow and indiscriminate horniness, nobody has a relative advantage in manipulating or lovebombing (heh) others.

However, most people's solution to the tradeoff between caution ("don't want to ruin our friendship", "don't stick your dick in crazy", and so on) and getting laid doesn't put all the weight on the former.

Even more convincing in favour of celibacy, which indeed has a long pedigree in many traditions of enlightenment.
