Oh, dude, seriously? That's not cool. Like, you should never pressure anyone into doing something they're not comfortable with, especially when it comes to stuff like that. Just respect your sister's boundaries and find healthier ways to explore your sexuality.
compliment her boobs
My Sister's Keeper is rated PG-13. This is due to language and sexually.
Just be totally honest with him/her and ask her if you want to experiment with me.
Sometimes, if they are unsure of their orientation.
my question is how can i convince my brother in law to get my sister to mental health
No. You are only gay if you are sexually attracted to men, but not women.
Ask her - she can only say yes or no.
prove/convince him that you're not a horndog bent on stripping his poor sister of her innocence.
it does happen. me and both my sisters did this. just touching, kissing, and orally.
Yes.
You can't. It's not really your business.
Tell her that she could be infected
