I gotta say, this is an improper question. Are you asking for permission to put aside your Christianity, are you really interjecting how you wish to condemn those who visit a brothel, or are you trying to “save” some souls here?
You are a free moral agent. You decide what you can and cannot do. Don’t let your preacher decide for you, nor any of us.
If it helps, your Bible says that all people are sinners, prostitution is a sin, Jesus talked to prostitutes compassionately. Read Luke 7:36-50.
