What can I buy my boyfriend for his birthday?????

Video game? Like if he has a favourite game in particular অথবা favourite character then আপনি could buy something related to it, that's what I've done.
I dunno, I haven't shopped for a boyfriend but when it comes to my brothers it's either video games অথবা car stuff. অথবা a nice শার্ট অথবা bodywash/colognes.
অথবা make him something, that's always best ^^ Just something that is special between the two of you~

Honestly though, guys aren't hard to ভান্দার for, I find girls আরো difficult to ভান্দার for :P

For some reason i read this in the beginning as 'Where can I buy myself a boyfriend" xD
anyways, yeah, video games he enjoys, right on.

I am not sure how anyone is hard to ভান্দার for. Just pay attention to things they like. If আপনি know them decently well it should be relatively easy. Video games,car stuff,movies,comic books,sport paraphernalia are among the stuff guys tend to enjoy.

your the only one who should know what he likes অথবা not
i mean we don't know the guy.....how are we supposed to help not all guys like same things

Guys aren't any আরো difficult than girls. The idea is to not worry about his gender and buy based on his interests. If he's into music, আপনি might look into getting a CD for some of his পছন্দ musicians. If he's into art, get him artistic media.
I used to buy my ex চা because he wanted to try as many different types of চা as humanly possible, so I would go and buy him obscure চা types. I even remember sending a box of American Breakfast চা all the way to Ireland for him to try.
