Me and my partner was having romance yesterday and he started sucking my right breast only softly but it was my first time.. And he gave massage to nipples also... After few minutes a dark coloured blood type liquid was on my bra. I was not knowing it.. And I feel my breast is little swelling and pain also.. But liquid is not flowing now.. Is it normal for first time?? Or I have to go to doctor? Please help me with this. Am afraid about this.. :(
