I think that is where it feels iffy to me, personally. Also, like, since you are asking this, there is a feeling of there being a power imbalance from you already so I would avoid it.
Don’t go off what people say on here. Men on here are particularly weird and misogynistic - and I say this living somewhere where I frequently get catcalled within 30 secs of stepping through the door.

A rule of thumb for weirdness in age difference is age/2+7, leaving you at 51/2+7=32,5. So going by that, 30 is a bit on the young side, which is obvious also from the fact that you felt the need to create this thread.
If one person would be in a position to judge you for it (or rightfully feel weird about it) it's your daughter. It's safe to say she seems cool with it, so whatever.
