Depends on how you define the term. I think if you stick to the Biblical definition probably not. If you go with the blanket cover of sodomy laws which in some states goes all the way to defining how vaginal intercourse is allowed to be performed (AZ's now banished sodomy laws missionary and female dominant missionary only, everything else was considered "sodomy") then definitely most people break those laws at least once in a while.

Even narrrowly defined as anal intercourse, why would you think not?

Anal intercourse occurs in the heterosexual community, which is de minimus, ten times the size of the heterosexual community.

It's not difficult to imagine that at least 1:10 heterosexual couples indulge in sodomy, is it?
