I have some thoughts on homosexual bonding, and there are studies to back them up.

There’s an old joke in the gay community: What does a lesbian bring on the second date? A U-Haul. What does a gay guy bring? A friend.

There’s some neurochemical truth to this joke. When two women have sex, the oxytocin surge can induce cuddling that lasts for days. Two male lovers, under the heavier influence of vasopressin, to say nothing of testosterone, may quickly feel ready to move on physically and emotionally after love-making.

In addition to the match in brain chemistry in same-sex couples, there’s evidence that one partner — gay or straight — can absorb the other’s sex and bonding chemicals; in a same-sex couple, this could heap on an extra helping of estrogen or testosterone.

Certainly, gay men and lesbian women love and bond the same way as straight people do. Their hypothalami produce the same exciting rushes of dopamine, and the same spurts of oxytocin and vasopressin. Sex creates the same association in the brain’s reward system between a sex partner and feeling great, inscribing a social memory that causes one person to prefer another.

In gay love, however, limbic resonance — that condition in which two people’s physiological states become attuned — may be, well, more resonant, because the lovers’ systems are more alike than those of a heterosexual pair.

So bungee jumping could be a great start — maybe even a better one — to a guy/guy date.
