My flexibility never decreased, so I don´t see the need to stretch in general.
I do however need more flexibility in the hips and shoulders for ultra-wide sumo squatting and Olympic lifting, so I´ll incorporate some mobility work for the hips (which doesn´t stretch the muscles and can be done before training without decreasing your strength for the day) and maybe a stretch or two after shoulder/pec work.
