Megan, a single medical student in her mid-20s, talks about her sex app experience: When out at a club a few months ago I decided to give one of these apps a try and turned on Blendr.

I believe removing yourself from an elongated one-on-one conversation with a man is a wise move for all married women.

Sure, married women can have male friends, but is it the best choice for the long-term health of your marriage? It’s no different when I meet a man that I think is cool. The problem with knowing everything about the someone of another gender is that you start to develop a bond.

It turned out that he was hanging out with friends at a bar across the street.

Feeling safe, with my friends all around, I texted back, asking him to come over and I'd buy him a drink.

I had only been working there a month so I wanted to take the chance to get to know everyone, male and female, over dinner and drinks.

I made my rounds over appetizers and when dinner was served, we all took our seats.

On occasion, my friend must excuse herself to attend to some matter.

And even rarer occasion, my husband needs to do something at the same time, leaving me in the presence of a friend’s husband.

Many times my husband and I sit at dinner with another married couple.

My husband and I engaged in conversations with the both of them throughout the evening.

Thanks to smartphone apps, seeking and finding fast hot casual sex has become, much like real estate, all about location. Before long using the app started to take over whatever free time I had.
