If you have anal sex and you bleed is it bad?

Yes: That shouldn't happen. You need to use lubrication (but not vaseline or petroleum jelly on a condom). If there is continued bleeding, see a doctor - it could be a rectal tear or fissure. That increases the risk of infection, including STDs as well.

Bleeding is a sign: Of trauma. There are risks w anal sex. Having anal receptive sex can lead to transmission of sexually transmitted diseases. Repeated anal sex may loosen/ weaken the anal sphincter affecting fecal continence. The anal/rectal mucosa is not well protected which makes it susceptible to tearing w penile penetration.
