It will certainly come as no surprise to hear that cold weather is going to reduce your sexual desire by a significant amount, as it is almost as if our body and those sensations effectively shut down over the winter. However, there is one thing that you can do to help the woman in your relationship to reach orgasm, and it is going to sound very strange and even difficult for you to understand how to tell her about it in advance.
This key point focuses on her feet, but not in the way that you are probably thinking.
Instead, it has been shown in various studies that if you are able to make sure that her feet are warm, by whatever means necessary, then the woman is 30% more likely to orgasm. It is just a strange anomaly whereby the comfort and warmth associated with your feet being like toast allows the body and mind to relax into what is actually going on. So, if you want to show that you are indeed a great lover and that you have her best interests at heart, then make sure she has some warm socks on, as it is certainly going to help.
