Heat leads to arousal?

Yes it do stay cool when you are taking it easy in heat at home alone

 

Definitely. It's warm this morning, I went to the gym and it was warm there. I'm home now, and if there were someone waiting for me I'd jump them in two seconds. But since there's not, I'd be just as happy getting myself off. But I'm gonna stick to my no PMO commitment...time for a cold shower.

Then again...when the seasons change and the Fall starts to settle in, if I open the window next to my bed and feel the cold breeze over my body; instant hard-on. Seems I just walk around with a hard-on no matter what. Holy shit, it's a good thing I found NoFap!

EDIT:
So all that talk about the Fall and cold breezes started getting to me. So I opted for the warm shower.
A couple of days ago I got one of those therapeutic muscle relief body washes. It has Spearmint, menthol, and eucalyptus:
IMPORTANT SAFETY TIP GUYS: Do not get that shit on your balls! You'll get that "cold burn" feeling. Thing is, I knew that. But I had such a hard workout I just wanted to relax and lather up. I got out of the shower ten minutes ago and my balls still burn. I'm such an idiot.

 

It really does. Warmth means bodily comfort and too much comfort leads to you saying "you know what, might as well do it...", which you know the result of. Hence why it might be harder to control your urges in this kind of environment, and especially during the spring and summer months. That is why I'd recommend two things:

1. Take cold showers (if you're not sick) whenever you can to cool off your body and distract your mind from whatever inappropriate actions it was tempted to do
2. Do vigorous exercise every day (or most days of the week). This way your blood starts flowing everywhere throughout your body and does not let get in excess in some areas. Also if you're extremely exhausted from exercising (preferably cardio), not even having the extra testosterone or adrenaline from doing so will be enough to get you to physically PMO.
