i've always had zero issues there. Drive, performance, whatever. My body has been in a perpetual 17 year old mode since i was 17. lol. I'm almost 44 now.
The only time i ever had any issues is when i was put on anti-anxiety medication. Effexor. Everything worked, but no O. I told the dr. that s#it had to go because i was a lot more tense if the equipment was malfunctioning.
She got a good laugh out of it and took me off the medication.
Everything has been fine since. I don't think i was as active when i was drinking because it just didn't occur to me as much.
