Is it normal that i look a lot like my boyfriends sister?

We are attracted to people that look similar to us, so maybe your bf and his sister look a bit alike? There is a lot of research supporting this observation ...

You should try telling people that you ARE his sister and see what they say.

kinky.

start lying and claiming you are... right before you make out in public.

I think our ideas of what attractiveness grow from what we see around us. My sister has long, dark hair, and I tend to end up with women with long, dark hair. Also, I went out with a good friend's sister even though everyone kept going on at me about how similar they looked. Maybe familiarity is comforting. Either way, you're not his sister, and there's no indication he wants to sleep with his sister. It's no biggie.

My bro married a girl that everyone gets confused thinking she's me and I'm her it's strange isn't it

I agree with mumbum . We are attracted to people who look like us.
I'm blonde, and I'm attached to dark blonde haired guys .

I once dated a really sweet guy (like 2 dates) but it weirded me out that he bore a resemblance to my brother (if my brother were to pick up a barbell every once in awhile). Despite the fact that this guy was sweet and considered attractive by onlookers, it churned my stomach the first 2 times he kissed me. But most people are attracted to what they grew up around, though... So maybe I'm the weird one.

Of course it's normal. There's 6 billion people on the planet. You're bound to look like one of them.
