Summer vs Winter

I ‘ve been doing various PE exercises for about 1,5 years.
Last November I felt a little tired and with a combination of a lot of work and a new relationship I did’t have time for it so I narrowed it down and even stopped it later for about 3 months.

I have started again 2-3 times a week just 1,5 months ago.
For these 2 years that I do PE I’ve noticed that I have clearly bigger gains during hotter months.
Most of my gains were from April to October. I am guessing it has to do with the heat of the environment and that you don’t have to heat up that much…

Makes sense to me. I was thinking the same thing when it came to growing my dick. The cold does have an effect on the penis. Making it shrivel up more often, so there is less blood flow.
