well if you think that he didnt want u too see, maybe you shouldnt bring it up, because it would be embarrassing for him and such. But if you think that he knew the risk of you seeing him and didnt care, go for it
accusing her of being a troll isn't necessary... @ Sammie don't end your life please, things seem down but it won't be like this forever, things will turn your way. you just have to attempt to find a positive in your life and focus on that
i don't think your a bi-sexual, you only get turned on by naked pictures of girls but you wouldn't be prepared to be in a relationship with them. Pretty normal and straight IMO. Anyways i think you know yourself the best and you shouldnt be worried about what you are.
i think it changes with what she is into, she may be the quite type in that case maybe just watcha movie at your house or something, but if she has a night life take her to a club, if shes the romantic type take her to a fancy restaurant
as the others have said, you need to stay motivated and have fun. some people have natural sporty talent, others have to work for it. im sure if you keep on practising you'll be good in no time!
i think if you being friends with him would make you happy then you should go for it. But before things change again talk to him about what has happened, and if he keeps being an asshole then...hit him!
