buying a dildo

Okay , so for one I'm an 18 year old freshman in college and I get all around stress . And there are times where I want to finger myself but it just doesn't cut it for me. I make my own money bank account so not worrying if mom questions me but I feel like since I don't have a guy around to satisfy my needs I feel like I should get one and since I don't have a roommate I don't have to worry about when I should/shouldn't use it but at the same time I'm not entirely sure if I want to get one . What should I do lmao
