First!

Clopfic, self insert, and an 11-2 like/dislike ratio? Impossible!!!

Hmmm... Good, very good. I shall await more.

I'm honestly not very sure what to make of this. A blatant self-insert I can live with and overall it's written decently but the second chapter is basically a giant wtf moment for me.

'I'll summon a human-turned-pony into my bedroom and offer him my virginity because bananas."

Not trying to be a hater but truly senseless plot devices such as this just come off as very bad to me. Overall your writing is good, and as a first attempt at any kind of story (let alone clop) it isn't terrible. My advice would be to give a bit more thought to the direction you want the story to go in first. Yes Twilight Sparkle is a fictional being but her personality and character has been established. Her actions were way too out of character for me.
Again, not trying to be a dick. Just offering an opinion. I can't upvote it myself but i don't feel it deserves a downvote either.

Terrible...

Thank you everyone for the comments and feedback so far. I will continue to work on this and will be using all of the feedback I've received thus far.

I like it.

At first I was like: Ahhh. Self-insert. Then I was like: Yep. That was worth it.
