Hi I think I have a serious issue. I am not sure if it's Physical or if it is just in my head. I'm 16 years old. I don't masturbate. I have recently started getting "busier" with my girlfriend. Every time we start getting pretty hot I feel this nauseous feeling in my stomach and I am afraid if i orgasm I will vomit. I feel light headed and it is very unpleasant. Has anyone heard anything this serious. I have read a few other cases of people feeling slightly nauseous or dizzy right after they orgasm but this feels so much more intense. Any response is greatly appreciated. Thank you.
