Advice on proposing

Emma-April
What are people's thoughts on same sex proposal. 
I want to propose to my girlfriend and people are saying I should ask permission of her father should that be a thing or not. 
To me I don't see why i should have to ask or why it should matter it makes me feel like I have to be a guy asking for permission in a lesbian relationship and I don't like it. 
Should I have to ask or not😣
