hey man, i'm in a similar situation as you. ever since i started jerkin it i always kinda knew my semen wasnt "normal" cuz it lacked sperm n clearly that would effect the consistency and volume to some extent. i'm in a relationship of nearly 3 years with a girl that i love very much and trust me... semen volume is not a concern. she's been with other guys before me and i'm sure they ejaculated more than i do but really... if anything, less is better haha. i know it's not "manly" but it's less mess, less to worry about, etc. sorry i'm not offering a solution to problem but just offering some wise words. i'd say most girls don't want a whole lot of semen from their partners... most think it's nasty!
