Anal Sex? I Wanna Try It But I Need Lubrication!?

I'm 16 Years Old And I Love Sex. I've Did It Almost 5 Times And It's Been Great...I've Just Never Climaxed. I Don't Know Why Though, The Pounding Feels Great. I Wanna Try Anal Sex, I'm Just Not Sure On How To Lubricate My Self. I've Did Some Research On Types Of Lubrication But The Only Thing That's Stopping Me Is My Age and Transportation. I Don't Drive Yet And I'm Only 16. Any Help? Online They've Said Not To Use Oils And Saliva But I Need Something. Any Help? Thank You! And No Critsicism, Judgement, Or Convincing Me On Not Doing It. I've Looked Online And Saw The Pros And Cons But I Need A Change And I Wanna Climax So Any Help On This Thank You!
