If you are concerned, then it wouldn't hurt to go to the doctors. But I have had sex with a past girlfriend and made her bleed so I shouldn't think it is that un common. If it is close to "that time of the month" then I think sex can cause slight bleeding. I'm no expert, only speaking from past experiance. If you bleed next time, try more lube. then go to the doctors.Hope you don't! Good luck.
Hi there,
I think you should go to the doctors just to check it out. One thing to bear in mind: If the person is that big, then it can irritate your bits big time, and so make you prone to infections like thrush and interstitial cystitis, so make sure you're really revved up (and raring to go!) before you do anything so it doesn't rub too much. Hope this helps...
