<human>: I [23 F] have recently lost quite a bit of weight. Nearing 70lbs. I never used to get cold at all, but lately I have been freezing ALL THE TIME! I can't be horny when I feel like an icicle. I just can't.

My boyfriend [28 M] on the other hand, bakes at anything above 67 degrees F. Naturally, this creates a huge problem when it comes to sexy time. 

We can't have the heat on because he goes flaccid when he is too hot, and we can't use fans because the airflow freezes me and makes me miserable. Does anyone have any suggestions?? I know this sounds silly but I am starting dreading having sex because I know I will freeze the whole time...

Could you distill the essence of the text into 1-3 sentences?
<bot>: You're hot and I'm cold, you're yes and I'm no, you're in then you're out, you're up then you're down.
