they tickle and hug each other in public (while their family don't allow non-married couples to even holding hands everywhere)
they like to touch each other's belly's skin (inside the cloth), because they say that it's soft, and they just like to touch it
they are about 30 years old and still sleep together in the same room, on the same king size bed
they often change clothes and shorts while the other is also in the room (except the underwear only)
they don't have any sexual intentions though, those are just habits.
they are my boyfriend and his big sister, who is 2 years older than him and she doesn't have a boyfriend yet. so is this only a jealousy from me, or is this relationship not right indeed? i need your opinions here, because if this is normal and only my jealousy, then i admit i'm wrong, i will change my own thought, and be more positive. but if the opposite, if their relationship is not right, what do you think i should do about it?
about the hugging thing, i'm okay with that though. i do think that's normal. maybe only jealousy since their family don't even allow us to hold hands (we do that while they're not around though. hey come on which couples don't even hold hands?). it's not because they don't like me or anything, they just don't allow non married couples to do that. so i can't understand how could they allow brothers and sisters to do those things then?
