OP, do you have a woman around? I noticed when I was single and started TRT and HCG, I didn’t experience an increase in libido whatsoever. Even up to 800 mg, when I “Bumped it up” I felt nothing. Once I was in the presence of my ex, who I didn’t even want to fuck when I was with her toward the end of our relationship, I suddenly became very aroused. Sometimes libido is mental as much as physical. I don’t experience very hard erections when just watching porn, but if I’m around a woman I’m comfortable and sexual with, it’s a whole different story. Libido also increases for me when I’m around women in general, not of my own bloodline obviously.
