It sounds to me from the descriptions of your own behavior, for you it’s just about curiousity more than anything, and I think when two girls who are completely straight do make out, that’s essentially what it boils down to. Unlike men, I don’t think women are by and large revulsed by the idea of kissing someone of the same sex…most straight men would have a hard time holding back the vomit reflex if trying to kiss another man. I think beyond that, it’s really hard to ascribe a defnitive label such as straight, bi or gay and apply it to all women throughout the spectrum of humanity, which is where I think the problem lies for most people.
Like several others who have chimed in, my initial reaction to this question was WHA??? Simply because you seem adamant in the idea that on the straight to gay continuum, you are talking simply about straight women. The logical disconnect here is that kissing is not a biological imperative like breathing or eating, and therefore there must be some sort of motive for engaging in this behavior.
The standard motivation most of us would ascribe to making out would be some sort of physical, sexual, biological attraction to the other person. It can certainly be an “intimacy” thing where it’s far less about sex and more about closeness, but because of the nature of the act, and of intimacy itself, one can not completely strip the act of tongue kissing from its sexual components. It’s a matter of what is derived from the act, which again points to motive…what does one HOPE to derive from the act.
Many have brought up the main motives one might have for kissing…the most obvious is sexual stimulation. But when we are adamant that sexual stimulation is not it, we must examine other possibilities. Yes, there are certainly straight women, who due to our culture which celebrates girl on girl action, find the ability to do this simply because they’re not repulsed by it to be an attention getting act as many have pointed out. As others have pointed out, again, if you have no revulsion to the act, when issues of curiousity, be they wanting to know what it feels like to kiss someone, wanting to practice, curiousity as to the difference between how men and women kiss, or curiousity about what it’s like to kiss a girl…these elements boil down to curiousity.
Now the only argument I have with the way you have presented this however is that if the implication is that something occassionally occurs outside the realms of a) curiousity, b) sexual intimacy and c) attention grabbing, tehn I think you might have to re-examine point b. I’m not wholly convinced that a 0 to 7 scale can completely underscore all the nuances of human sexuality for BOTH sexes. As you say, a woman may have absolutely no desire to date or even have intercourse with another woman, nor does she get the same feeling of desire welling up when kissing a woman as she does when kissing a man, but she may be getting “something” out of it. Something I’d say that is a bit more ethereal than just the urge to merge. Again, it boils down to an issue of motive…in order to engage in the activity, you have to be getting SOMETHING out of it.
