Grind'r goes like that for 95% of the message received :
him : Hey
me : Hello
him : Top or bottom
me : No anal whatsoever ( giving or receiving )
him : You are going to love my big cock up you ass
me : Nothing goes up my arse , i mentioned earlier i do not do ANAL ..
him : I am going to love your big cock inside me
me : Have a great time with someone else , Cheers
Not weird , not enjoyable either ...
