Bottom Problem

[Legend1977]

Hi to all . So i want your advise . Im bottom but actually i do sex with transsexuals . I like a lot to use dildos and now about 8 months from now i use a huge dildo 23cm . Oh my god i like it so so much .Iwas trying to get it all but at first it was so hard . As the days goes by finally i made it with a lot of oils . The main problem is that sometimes when i do it hard i see some blood , not a lot , just a little . Not every time happens but 3 or 4 times . I use it almost day by day . Do u have any idea what is it ? I forgot to mention that i was see my doctor and i was getting colonoscopy to see how i was because i was suffering with some pain before i was going at the toillet and all it was good . Please i want your answers .
