hi LPSG! im a 5'6 asian female and my boyfriend is a 6'2 asian male.. im kinda thick on the legs. tall/short couple but theres a couple of problems. his unit is only 5 inches long! it looks like a baseball bat and his girth is probably 5.3 inches(yes i've measured!!) i always thought a taller man would have a bigger unit but i assumed wrong! the next problem is sometimes he cums too quick.. he told me when he masturbated he'd cum within a minute in order to not get caught(lol!) what positions can i do so me and my boyfriend can work this out?
