Researchers at the University of Pittsburgh Medical School studied this in 1997. You can read it here:

CONCLUSIONS: Passive ARI is associated with decreased resting anal canal pressures, but total pressures are normal. There were no IAS or EAS defects, as well as no fecal incontinence, in our subjects. Better relaxation of the ARI subjects during anal canal manometry may explain the lower resting pressures.

So, what that means (from my non-medico perspective) is: When walking around minding your own business, the anus of someone who doesn't engage in anal sex regularly will be tighter than someone who does - and that's most likely because a relaxed sphincter is important to safe anal sex. But having anal sex will not cause fecal incontinence, and your ability to tighten your anus will not change.
I haven't come across any serious, scientifically based literature that disputes these findings.
