just start out slower with him and you can go rougher a little later :)
Hi Lets take things this way, your bleeding is proberly form some small splits from as you rough sex, just keep them clean a couple of times a day useing a warm salt water wash, this should see you ok in a couple of days.
And next time you see take along some KY jelly, or some kind of lubrication, but I would give it a few days till you get back in the saddle again.
Good Luck
it's not serious you need to apply lubricants next time especially because he's bigger than you're used to
it will stop just check if there's any wounds and keep them clean
gd luck
