Kalvintage; Freaked out!

So I was playing on this game site today, when all a sudden one of the dudes I added as a friend messaged me saying:

"Hey I'm a bi dude is that okay?"

Trying not be be rude, I replied:

"Lol that's cool"

Then out of nowhere he started talking about how one time where he and his friend was high, they decided to give his friend fellatio. He then also asked me what was the freakiest sexual thing I've done. Mannn, What's up with this guy? Hahaha.
