the feeling of the "peeing" is him hitting your G-spot.. yes its natural to feel like that.
Its normal not to have orgasms with your boyfriend.. it is heartbreaking.. and i think you should tell him that youve been faking it.
Its a shot to the EGO for him.. but tell him so you can work through it.
(easier said than done right?)
I faked orgasms for 2 years.. then told him.. he was upset for a while.. he stopped having sex with me.. then he finally came around and started to try new things..
I orgasm fine now.. dont be afraid.. he will come around
