Dear LIB readers: Is it right for a married woman to publicly buy condoms?

From a female LIB reader

I'm a happily married woman with two lovely boys in my early thirties. My husband and I are recently planning to have another child and this time,we want to try the Pre-sex selection method and see if we can skew the odds to our advantage and get a baby girl.Not that we would mind if it wasn't a girl but we want to have our last child and try our luck in the process.

The way it works is since I need to monitor my cycle for a couple of months,I'm not on any contraceptive and we've agreed to use condoms during intercourse.The only issue is that my husband sometimes forgets to buy them before coming home and then we've ended up making love without condoms twice now.

My question is "Is it right for a married woman to publicly buy condoms?" Because I'm seriously considering doing that to avoid conceiving before the planned date.
