I am a 20 year old female and I lost my virginity last night and I am on birth control and my boyfriend used a condom as well. The condom didnt break because when he took everything off, nothing leaked. I went to the bathroom about 12 hours later and there was this white stringy clump that was rather large and kinda looked either like discharge or maybe some sort of skin? I've never seen that before and wanted to know what it could be? I thought maybe the hymen if that is even possible, but I have no idea. Just looking for an answer, thanks!
