Yes, this is normal practice from what I've seen in my 47 years of life. Again, from what I've seen both engage in on social media, beer pong at his house, etc... leads me to believe they've had sexual relations in their time together dating back to school, yes, I believe that, nor is there anything wrong with consenting adults behaving this way. If not, so be it. ¯\_(ツ)_/¯

Not to mention you just called me an incel, lol. Self awareness much?
