Amira hi I'm thinking about this same stuff and I think it's something you've got to want for yourself. Some of what you said - like pride and stuff - I don't think is a good reason. Don't do it for religion or your future husband or anyone else - I think I had this idea and I wasn't calm about it - just thinking he won't care or think it's weird.
So yeah do you feel calm - like thinking there won't be any of that for years - do you feel calm about that and know why you decide it?
And what @youdontknowme said is good and probably you could not not give up the unbelted time at all just like promise to not to have any time alone.
And yeah what @Sin said go read that one again see you need decide what makes you happy not what others are hoping you decide.
