'Bedroom' problems (bit rude)

A married couple were having problems in the bedroom.

The wife said to her husband, I’m sick of this! I’m going to the chemist tomorrow!

In the morning she goes to the chemist, talking to the assistant, can I speak to the pharmacist please?

The Male pharmacist comes out, how can I help madam? he asks.

She explains the problem and says, would those viagra help?

Without a doubt he replied, I take them everyday.

Can you get it over the counter? She replied.

Spoiler:

Only if I take two, he said.
