Ok so I've been with my current girlfriend a year now and I'm starting to notice my sex drive doing strange things. Back 9 months ago we would quite often spend all of a day in bed having sex and now I just completely lack any sex drive. If it wasn't for her sexual needs I probably wouldn't have sex at all. Generally I can only go a few days without needing some sort of sexual stimulation but at the present time I honestly feel like I could go weeks without any form of stimuli. I don't believe it's related to not being attracted to her anymore because I still find her more attractive than other women and it seems to be a universal thing, no body is as sexually attractive as they were. Also I'm pretty sure I'm not gay or bisexual either for the record. Lastly my lifestyle hasn't changed at all recently, sure I'm not doing as much sport as I did 3 months ago but when I was training 7 days a week I was just exhausted all the time. Surely casual jogs and hockey twice a week wouldn't sap my sexual energies. Other than that I'm a 21 year old uni/college student so I don't see why my sex drive has suddenly slowed down so much. Has anyone else experienced something like this before? a fluctuating sex drive despite no great changes in lifestyle?
