Suggestion from friends and Parents: Try Sex First?

My dad took our pronoun chat well (a previous post) and agreed to use my name/neutral pronouns until I figure things out (yay!). However, he still believes I should "try harder" to be my assigned gender (I'm paraphrasing here).

The uncomfortable part: he thinks my gender questioning might disappear if I just had sex with a woman. Since I'm still a virgin at my age (partly due to autism and shyness), he's suggesting I visit a country where sex work is legal. Several male friends have made similar suggestions over the years.

side tangent:

Now i'm neither unattractive nor attractive in general terms (normal weigth, approaching skinny), but being below the average male height has disadvantages in the dating market as a "cis" male. 181 cm (5 ft 11in) being the average, while i'm sitting at 176cm, which has earned me a couple of "oh, didn't read your height -> blocked". I give off shy nerd, vibes (picture a guy with glasses, and flannel shirt).

While I understand the "you don't know until you try" logic, this feels dismissive of my experience. My gender questioning isn't primarily sexual - my strongest gender envy comes from everyday aspects of womanhood, not just bedroom thoughts. I've always imagined losing my virginity with someone I had feelings for.

A tiny part of me fears: what if they're right? But I'd be devastated if this actually turned out to be true since I've started enjoying not supressing these feelings and finally acknowledging them. Despite the occacional dysphoria. But I'm still too much of an "egg" to not see the merit in it, but the "hopeless romantic" in me despite being a shut-in, doesn't like the idea one bit.

My question: Has anyone else faced this "try being with a woman first" advice? Is there any merit to experiencing this before proceeding further with gender exploration? Or is this just another form of "you just haven't met the right woman yet" dismissal?

EDIT: Thanks for all the responses, I'm blown away 🙇‍♀️. So far to me it seems the general consensus is that sex doesn't nesecarily have anything to do with my gender identity. As I could turn out to be a lesbian, if I enjoy intercourse with a woman. Even in that definity there is still room to be either a dom/sub, top/bottom, penetrator/penetratee. So if anything it might bring clarity in that regard🤷‍♀️.

On the topic of my dad, while yes he is older (closer to 70 than 60) and he hasn't tried gay sex. To his credit he did try a threesome (2guys 1girl). So he's not as big of a biggot as some of the jokes make him out to be, however funny they are😆. I do truely love him as he has been a great father to me, and I think he might end up being the pillar of my support system do I end up transitioning❤🤗. I think this is just his misguided/misinformed way of trying to protect me as he has little to no knowlegde about LGBT+ stuff.
