My life of anal experiences are a few years apart as it isn't always every girls cup of tea. Usually I will give the girl's anus a little light tickle at some point and see how it's received. Many girls might murmur something like "No No" or move their hand to move focus to another area. It doesn't really worry me.

The non-working girls are more open to being introduced to anal. I might spend months teasing their ass and anus until some random night when their hip motion moves from moving side to side to that moment where she starts to pushback on my finger. That might happen over the next few nights together, she finds out it is good for her and then it's the girl that suggests trying anal. I can attest to this working with four girls so far.

I am interested to know if people make progress on anal in shops or if it is always off limits?
