In brief: May Be Prostate

A swollen prostate/seminal vesicles causes pain to occur in the rectum. If it is only after ejaculation then more likely it isn't inflammation; that represents spasm of the pelvis/genital muscles.
To help it, practice squeezing the internal muscle you use to stop going while peeing. Once you can do this without urinating, focus on squeezing then completely relaxing. This may reduce the pain.
