I had a similar experience. My (heterosexual) ex used to frequently use forums like Grindr, and it is very likely he used to use it for hook-ups, but when ‘caught out’ or questioned, would blame the coke. My theory is that that is a side of him that he was deeply ashamed of and the cocaine allowed for the freedom of self. I think cocaine allows and justifies the desire, but doesn’t create something that isn’t there already.
