Sexually, here's what I've noticed: higher AR affinity drugs always increase my libido (not alot of deca experience, so I can't comment on that drug per se). If I have ANYthing aromatizing, I have no performance issues. I seem to have found a sweet spot with 50-75mg/day TA and 20mg/day dbol, plus HCG. At these dosages, I don't have any estrogenic sides, and generally run without an AI (but always on hand). I've never messed with caber or anything else, so I can't comment on any effects they might have, but I've been told they are nice for libido and performance weather you're on AAS or not.
Nothing gets me ramped up sexually like test. 100mg/day suspension was wild. Also, test gives me increased erection hardness, and nothing else seems to have that effect, except MAYBE Proviron.
I hope this is of some value.
