I don't. No I never have tried it and admittedly I am bisexual, I'm just not very sexually attracted to men or I just can't imagine myself being with one unless he's absolutely amazing, so I identify as a lesbian (not many people know this, I just needed to get that out into the open so I can say what I've always wanted to say about this topic). I think trying out something like that just to for the sake of being open minded would be damaging for me so I'd prefer not to do it (damaging because I know I'm not attracted to men that way and because of the way I view it).
I'm in no way a feminist, I think if someone has read at least twenty of any of my posts they'd see that, but I do think the act of fellatio is degrading to a woman but for the reason of how most men talk about it and how society reflects the importance of it and conveys the act in such a demeaning way.
But it's not only that, I know my feelings towards a mere sexual act are irrational but they're pretty strong. I was cheated on by my ex, I asked her about it and she gave me too many details. Then that just made me bitter towards boys my age (this isn't what made me identify as a lesbian, this was well after I discovered I was one) but then it escalated when I observed people. When I overheard things and when I was accidentally around my friends having a "girly" conversations or around my friendboys talking about experiences that they had. They never really understood why it made me so touchy and why I wanted to change the topic so badly. Especially when they were talking about a girl I used to like.
Girls were mindlessly pleasing boys this way in search of acceptance, because they'd seen it in movies, on tv, it's everywhere and everyone knows what it means! The whole act of women getting down on their knees. I don't want my girl to get down on her knees when she's pleasing me! As if it's some act of submissiveness, of beggary. And these girls being as young as twelve to thirteen-years-old, being the little innocent girls I'd grown up with.
Tbh for these reasons, if I ever do find myself in a relationship with a man, I can't imagining ever pleasing him this way, which isn't fair on him, I know. Which is why I'm better of with women anyway.
Edit: It also looks very uncomfortable. If women can get sick by putting their finger down their throat...you know.
