Something extra?

I'm masturbate all the time. Probably way to much for a young girl but anyways I get off but I would like a faster method. I would rather not buy anything because my mom is a co sign on my credit card and she will see whatever I buy and we are not that close. So is there like house hold items that really get you guys off or some way to like position my dildo to climax faster. Is there anything that my boyfriend can do that will make sex a lot more enjoyable for me? Sorry this is long.
