Normal? Not in my experience... (and when it comes to Anal, we're talking a LOT of experience!) Sounds like you need a lot more prep before your boyfriends enters your backdoor. I don't know if you engage in much foreplay before he enters you, but you should be very aroused and very lubed before penetration. Even if it's that time of the month, you can stimulate your clit... have him finger your butt hole first to help relax and stretch you. I can only remember once or twice when there has been any bleeding from anal play and that's been from being a little too rough... lots of fingers and dildos... So I advise to take it slow, and also wait a few DAYS for it to heal if you bleed, maybe a week... I don't think one day is enough time. Good luck! And be safe...
