[T] My college GF turned me into a Femboy

First year in college I met a very hot girl and we ended up dating . She was smart and quite known in college.
I always had a big ass and legs which would get me harassed a lot by guys in gym or bullied .. so I wasn’t the manliest man but I was happy with my gf a lot and I could pleasure her. But she also owned toys and stuff and after a while she would start fingering me while bj and stuff like that and even if I wasn’t really into it , I loved her so I let her , plus it felt good sometimes.. the finger turned into toys and so on and to spice up our sex life she would even suggest roleplays where she dresses me and the dresses would get more and more feminine and I kinda did it out of love most of it .. until one day she came up with a chatisty cage and convinced me to wear it to show her my love.. she began being more and more dominant …
until one day , I found out that she cheats on me with a lot of the hot guys at school… and she would even tell them about what she does to me and they would tell her to do other stuff to keep me under her leash .. which worked because even if I got mad and broke up with her , I ended up begging her because I was locked and she controlled it …

[T] i hated the fact that I got hard and came just from seeing my girlfriend with other men

When I was 18 I dated my first gf ; she was alright looks wise, but she was very adventurous and straightforward and I was quite shy, so she kinda always took control , she was more experienced than me and just overall more controlling ..

Our relationship was normal at the start but then she kept wanting to try new things and doing stuff and she wouldn’t really take no for an answer cause I was just a bf that she can push over

Our sex life was okay, but I wasn’t gifted down there so she just always taught me how to eat her out and like sometimes she would just make me eat her out without fucking or anything and that happened often…

Until one day , she kinda put the idea in my head that I’m small down there and that she needs something bigger , so I wore a strapon for her , but she would complain cause it’s fake and long story short, she insisted on fucking someone big.

I didn’t like the idea , I was jealous and afraid and all… but she kept insisting telling me I can be there and it will only be for sex etc..
