Should I stop chatting to this guy?

I have recently chatted to a much younger man on line. i am 49 he is 19. Things got very hot.I hope i am not leading him on. To be honest i think i am, but the emotions i feel during our chats are so intense and pleasurable that i don't want to give them up. This is all done in secret late at night -in the early hours here - my husband would be upset if he found out. I know i must not do it again, but hell he is beautiful and sexy.
