Forget all the questionable stuff about female orgasm. The fact is that he ejaculated about a tablespoon of semen into you. Added to some lubrication of your own, the drainage gives a wetspot. "The wetspot" is a constant subject of jokes. You are normal. That happens.

The bleeding will likely stop with your hymen all the way gone; it sometimes takes a bit of sex to get rid of it. But his fingernails are a possibility.

depending how much there was it was either female ejaculation or urine. some women are gifted enough to be able to ejaculate when they orgasm, others urinate which can be embarrasing for the girl involved but the guys seem to love it. either way its normal but if it is urine you should work on exercises for your pc muscles, the same as a woman does after giving birth. if this doesnt work then you should see your gp. also, if your guy is fingering you and you bleed afterwards, he probably has a rough nail or something that has caused a scratch. be very careful with that as it can get infected. tell your bloke to file his nails ;¬) and good for you for your 'guy given' orgasm!

yes, you being wet after an orgasm is perfectly normal...my girlfriend gets really, really, really wet durring forplay and durring sex, making it much easier for us. when she cums, oh man...it's alot of juice, but i like it....if your bleeding when he fingers, you probably are really tight and don't stick too many things up there huh? if you don't, then it's normal and you should bleed.....if you do use tampons and finger yourself, then he might be going too hard.
