I had a physical attachment woth my gf.Day before tomorrow.we were naked....and I pushed my penis on her vagina..but didn't penetrate...after sometime I felt diferent and my sperm comes out..when it came..I slightly removed the penis at a small distance form vagina..that time she faced no beeding..
but after 19 hrs she had a bleeding..and we are confused now...that had she really lost the virginity?..or its..period...because her period time is on 27 th of this month...
and she cis feeling pain...she is bleeding..and amount of blood is less..than that of the period..
