What do I do

Idk if 14 is too young to masturbate but I have been doing it since i was 13 and I don’t know how or when to masturbate I usually do it in the shower and just finger myself but I feel like I don’t get a strong enough orgasm. What can I do to get a stronger orgasm? cause when I start really getting into I feel like I need to pee and I stop is there anything else I could use? apart from my fingers and a dildo or vibrator because I wouldn’t be comfortable buying one
