is it normal that...

[TightBottom]

so i have recently come to terms with being bisexual (a bottom bi) and I've started using toys while masturbating. I've used fingers and small objects in the past but i decided to splurge and get a dildo. I've noticed that when i defecate later in the day after using it, there's a small amount of blood in my stool.. is this normal? my toy isn't that large, only 6&1/2 inches and not abnormally thick.
