Been dating 18yo HB7 for a year and a half. she always texts me first to fuck and do shit, she sucks me off, after saying she doesn't do that for the first month and now does rimjobs.

Been trying to push for more sexual limits, like threesomes, anal, going to stripclubs, but meet a solid wall for the last year, saying things like she doesnt like to share me, etc..

Is she just a prude or does it mean I am not her best chad?
