Text message

I was going through my boyfriends phone and I found a message from a local number but was not saved as a contact in his phone. There conversation was deleted partially, so there were only 2 messages. It took place on a Tuesday night at 1am.  The first message was from this person saying "nah Wednesday is strictly hump day, quick f**k n suck and keep it pushin...motorboatin is strictly Mondays and Thursdays" and my boyfriend responded "I can live with that regiment". I don't know what  make of this conversation. Could it be a friend talking about something? I don't want to overthink it but my first thought was that it sounds like a prostitute or something. The area code of that number is from a city very close by where there are many prostitjtes and my boyfriend works in this city a lot. I know it sounds stupid but I really don't know about this stuff. Do some prostitutes offer different services on different days ? Motor boating strictly on certain days sounds a bit odd, almost like its a joke. I don't know. I just want to know if my boyfriend is talking to a prostitut. Any input is appreciated.
