So my boyfriend is 18 and I’m 17 .

All his girlfriends have been ginger 😬 (he is kinda ginger him self ) I used his phone while mine was dead and in one of his tabs was the search Trans porn . It was a red head trans who in a reall wired way looked like his Ex ( a woman ) in the stages before we was official he talked to a few ginger girls behind my back . This sounds really messed up and I’m laughing while I type this 😂😳 he also sent a pic of him self to what I know to be a guy on a fake snapchat account who apparently before me and him met faked being a girl and got some kinda information on him and this guy apparently blackmailed him into sending this pic . He posed with his bum in the mirror like he kinda liked it?😳 it was sent to him on snap to scare him but I opened it and saved the picture to my phone and asked him about it . He ain’t showed anything els that would make me think he’s gay or anything . He obviously likes stuff like anal witch was something we only did once months ago as it’s not my thing he likes thumbs in my bum as well but I thought it’s normal ? Idk I sound mad but some advice? I thought we was kinda normal people but idk now😂🙄this was around 2/3 months ago now and we haven’t spoken about it iv tried and he’s lost his shit with me every time 😂😬help
