I think it's the physical appearance of a penis that makes me uncomfortable, female parts bother me too, but because I’m a woman and have the same parts, it doesn't disturb me as much. I find myself averting my eyes, flinching or grimacing whenever I encounter one (penis), but when I see one on my screen (say a movie), it looks like a regular body part.
Now you might be wondering why some insane stranger decided to start writing about how male genitalia made her feel, and why she decided to post it, the answer is simple-
This stranger is fed up with men. (And clearly has a weird ass thought process which is why she started this piece talking about a penis, forgive me if I scarred you).
If I wasn't asexual I'd be a lesbian, or a bisexual that liked men that let me be in control (of their entire life), but will mostly date women. I'm already masc presenting to begin with, or a stud in simpler terms.
It's not like I have a problem with all men, it's just that all the men I grew up around, schooled with and worked with, and have had a brief encounter with has a problem with my gender or are disgustingly vulgar and disrespectful towards females.
They make rape jokes, pedophilia jokes, body shame women (stretch marks, dark inner thighs, flat chests, sagging chests, things they have little to no control over), are unbearably loud, find every avenue to touch females indecently, have personal hygiene below standard, jump to plain stupid conclusions, cannot recieve what they dish out, refuse to listen when I say ‘no’, needs a slave bearing the title of girlfriend or wife, act like they should have the right over women's bodies and actions, think (and even say) that they are superior to women and when I ask how, all of them say it's because they have a penis, in one way or the other. The list goes on.
I regard them as much as I regard papaya, hot chocolate, soyabean, dates, sweet corn, sycamore fruit, RASINS, mayonnaise, cake, milk chocolate, pap, cold noodles, foods I can't stand enough to put in my mouth.
Women on the other hand are in the same classification as alcohol, dark chocolate, caramel, cigarettes, gummy bears, lime, sweetened yoghurt, sour worms, crocheting.
Sometimes good, usually not good for my health and mostly bad habits.
Even though they annoy me, I don't mind when they are the ones that objectify me because they know lines not to cross and know not to take things to far. Most importantly they know what the word ‘no’ means.
I can ask for nothing more perfect.

P. S; just incase you're yet to notice, in addition to being insane, I'm very biased.
C'est fini. Merci.
