Boyfriend fingered me and now my vagina is really sore

Please don't let him to fingering you, maybe he don't have any experience

Soreness can come through, inter alia, lack of lubrication, a rough finger or nail. It can also come from rubbing an existing damaged area.

However, I am unclear what you were doing, and where the raw spot is, and what it looks like. Can you see it? You are a little light on detail.

Your vagina is the muscular tube that connects your uterus to the outside. It is the receptacle for the penis in sexual intercourse, and the birth canal when a baby is born. Are you saying the is a raw spot in your vagina, or on the vaginal entrance? Was he fingering your vagina roughly in a different way this time? Were you as well lubricated?

Maybe the sore spot is on your vulva, maybe between the labia? Was he fingering your clit? Again were you well lubricated? Have you examined his fingers?

Depending on you hygiene and sexual habits, you might have picked up an STI! You could try come cream like sudocrem, but if there is any chance it might be an STI, seek medical attention urgently. Avoid sexual contact until you have had it diagnosed and professionally treated.

Hope this helps
