I'm 32 years old and I'm guessing this is what getting old feels like. It is only 12pm, I'm horny, my girl is asleep, and I'm too tired to jack off.
Wait til you're 35+, that was the breakingpoint for me.
Before 35 i still felt like a 20-year old regarding constitution, energy etc
I could party for 2 weeks straight abroad when it was 40+ celcius without that much effort.
Still energy in the tank and could still eat heavy. Sexual stamina was great before 35 as well.
Could still drink, party, train like when i was 20 without repercussions or consequences. Even at 30-34 yo.
Nowadays i get tired when the heat is 30+.
