It's unlikely that he broke your hymen, unless he's trying to force more fingers in there than 1 or 2. Also, just because your hymen is broken, doesn't mean you're no longer a virgin. Most girls' hymens will break over time from activities like riding a bike or horse, or even just playing sports. It happens. Just make sure you're plenty wet and his nails are trimmed before he begins. It's only comman courtesy.
Hi there. Well, you just never know. It could be that he nicked you, it is a bit of blood from a period coming, he broke your hymen (or started to), etc. You are engaging in sexual activity, so things happen. If you aren't ready, ask him to respect that. If you are ready, then buy some condoms just in case. good luck
Does he trim his nails before fingering you?
