I am going out with this gal and my brother just came home from the united states and the gal that he is going out with who happens to be my girlfriend's sister .so what do i do because from the school of thought they say it is incest.what do i do.mind you am serious with this girl and we are planning to get married next year february.

Of course it's not incest. You are not related to the girls at all.

Anyway I'm confused. Is she his wife or just his girlfriend? Not that it makes any difference really.

they are getting married next month

Set of male twins get married to set of female twins and they are not in any sense incest. Go ahead and marry her if you desire, if you desire, it is not incest at all.

i need more light on dis issue as well

Depends on which part of the country u come from
In some places,its an incest.They claim that ur in-laws are ur brethren,marriage authomatically makes ur in-laws ur relatives.
lol,tight situation.Its either u or ur older bros

first come, first serve! get married next week and let your brother worry about the question of incest 

some cultures don't allow that.

Not allowed in the yoruba culture. Your in-laws are your "family"

i see no reason why u cant, she no relate to you.
But some dumb culture of ours will say otherwise, and this is one of the cultures that i hate with passion.

I personally don't think there's anything wrong. . .

Seek the opinion of your parents to ascertain if your relationship will be acceptable in your culture or not. Various societies will react positively or negatively to this love 'conundrum'.

Best wishes.

It's not incest .
It's allowed in Igboland if you're Igbo,you folks are not related
If your parents are OK with it why not?

@Poster,are u Igbo and which part are u from?
Its NOT allowed in the WHOLE of igboland.

doesnt make much sense to me, marraige is RIGHT , marry anyone if u luv him/her since u aint bloodzzzz

my people use to say that if a road is good we walk it twise, therefore it may not really matter provided the people involved are sincere to themselves. but some culture reject that is ok.

zinco:

my people use to say that if a road is good we walk it twise,

Zinco,abi me and u come from d same place?
In my own case,my people used to say "na land wen good person dey farm twice"
@Poster,carry own jari
incestuous relationship can only exist btw a broda and a sister,or a father and daughter,
not btw inlaws.

lol use common sense, ahhn, incest ko incest ni, psheeewwww,

It depends on is acceptable in your area but it is not in anyway acceptable in our own culture-Yoruba land. Both wives will surely have differeces in the future which may affect your family.

No you can't and you shouldn't, you can't marry your in-law

LOOK 4 ANOTHER WOMAN B4 ITS TOO LATE
TO AVOID LOADING THE GIRL
TAKE CARE

dude it seams ur a freak or sumtin. Dont u and your broda or ur wuld be wife talk. If yu did u wuldnt b in dis situation. If u marry her u wuld be marrying ur second sista in-law.
Try to make her see reason why you have to call it off.

Some of this culture stuff can be quite dump atimes.go ahead man and marry the wman u love as long as u ar not blood like the bible also condemns.

guy go ahead and marry her. is she your sister or cousin? hell NO! go ahead joor and marry her if you want to.

guy go ahead and marry her. is she your sister or cousin? hell NO! go ahead joor and marry her if you want to.

The coast is clear!
No blood ties! Faya on with the marriage!

Una Don marry now?

So did y'all get married
