Have sex with my half sister brother?

Sounds mischievous.
Did you have a question, or are you simply boasting?

not a good idea

hahahahaha hahahahah loool. stop, please don't ruin your family this way

ugh. don't. the family dynamic messes up the relationship very quickly. much better to NOT get into a possible HUGE mess.

So u both share your half sister but u both have different parents right ? If so well technically u aren't blood but by the way u sound u sound young and shouldnt be letting any guy go straight to wanting to have sex with u that just sounds like he wants to use u ..young guys just basically girl crazy and want one thing but u didn't ask any of that So lol Imma say leave it alone that will just be complicating and if I was your sister (and if she young pretend she got older) would feel weirded out that my sibling would hook up don't do it

If your half sister/brother is a true hermaphrodite then they may be infertile, in which case it's probably OK - no chance malformed babies.

no really don't understand is it your 1/2 sisters brother are you a male or a female

Ew
