Real talk this is kind of how I determined I've always been ace.
Completely incomprehensible ace rant here but after the first blowjob I had basically the same thought but, like, is anyone having fun here? Sex feels great, ideally there's lots of opportunity for mutual satisfaction there, but oral is like, one person gradually getting sore/frustrated while the other person wonders what the pussy's gonna be like later. I've had a variety of blowjobs but even the one girl who said that's just how she likes to spend an afternoon, who I totally believe, made it pretty one sided when she was like "no seriously you can read or something".
And of course to be totally contrarian I do like eating girls out but there is a point where it's like, okay, yeah, we should switch it up. It's fun and intimate but if it isn't a pleasant way to draw out the activity then why bother?
And yeah lotta years in ace denial. Pretty sure it was less of a sex drive and more like a special interest.
