Really tired of my parents thinking me being sex repulsed is "teenage embarrasment"

I am not out to anyone yet, so my parents think I have just not reached that phase in life yet where I am ready for this kind of topic (i am almost 17, I do have time but most people my age are already past that), but it's really annoying that every time I get disgusted in romance / sex scenes in movies it gets passed off as being immature or too young mentally. Are people not allowed to be uncomfortable with some topics, regardless of age? I don't get it

"How it feels to chew 5 Gum" - for the allos?

Got into a debate about this over Thanksgiving, involving family friends who have a tendency to subject me to light teasing for being the resident asexual. I used the word "stimulate" in a sentence which got a 😏 whoa whoa whoa✋ reaction, to which I said it's a normal word, unless they think 5 Gum commercials are inherently horny ("stimulate your senses" is the tagline). They said that's EXACTLY what those commercials were about. I'm a bit young for those commercials and apparently haven't seen all of them so I'm okay being wrong, I would just like my fellow aces to weigh in - are the old 5 Gum commercials about sex?

Edit: disregard these guys are full of shit they just dead ass told me a Geico commercial was "more sexual than not" because it had a football player in it
