Abnormal way to masturbate

Hi,

I have a very abnormal way to masturbate. I push my (soft) penis against an edge or corner of a furniture then I put my hand on the surface of that furniture to lift my legs. Then, I sway them from side to side. I can orgasm in less than 30 seconds and there is no need for lube. You should try this too. Anyways, my problem is I have never orgasmed before other than using this method. When I try masturbating normally, I climax then I urine. No orgasm, no cum. How do I solve this problem?

Thanks.
