The product is pads for women. The pad is represented as one that will provide confidence and comfort for women due to its comparison to the male model. The ad depicts the man as a strong and secure figure in a woman's life, and is further objectified with his buff body. It is clearly a "cultural commentary on male sexuality, glamour, and body norms and ideal." (p. 129) Even his stance portrays him as a strong male... you can see that he's closing a safe, further establishing him as a secure figure. Even the message of money as security is sent in this ad.
On a side note...I found an interesting ad from a magazine in the UK from the 80s that pays homage to Gloria Steinem's "If Men Could Menstruate"
