A very worthy motive my friend
I have found that some of the meds I have taken killed my libido. When I was binging hard on pregabalin, I basically had a useless floppy appendage that was only designed for eliminating waste. I even found that I wasn't staring at ass all the time either. Probably the worst effect of the drug, and this floppy shitiness lasted for a few months after I quit. In fact, its never really returned in full intensity, but I am also taking bupe and seroquel (not as often as I should because I really dislike it).
I rarely feel horny and filled with lust, a feeling I truly miss. But, if I stare at porn and fanatise for long enough, I get hard and can cum. Of course, if I am caressing and squeezing the real thing bent over in front of me, I am replete with desire. However, I miss that lustful hunger.

Better than being psychotic and suicidal though.
You will probably get used to this effect but hey you might just need t develop a new fetish. I did find that smoking pot would get me pretty revved up but the body didn't always agree.
