Ever since my boyfriend gradually became more sexually aggressive, he's started showing interest in masochistic pleasures! I really want to keep him to myself, but his desires are just too intense to control. He gets so turned on, saying things like "I want even more stimulation" and "I don't care how many times I cum, even male squirting is fine," jerking off excessively until he's drenched in sweat and erupting with male orgasms. In the end, he's completely awakened as an aggressive nymphomaniac.
