As a female here.....(and I do second everything ssmguy said)
Uh...... no other way to say this but......
ya know............. . . . . . anal can feel rrreeeeeeeeeaaaallly good.
I'll avoid adding anything else or tips or whatever unless I'm asked.
FYI: I also teach comprehensive sexuality courses (for about 10 years now)-- I have no problem talking about or describing anything having to do with any type of sexual act.
