A hairdryer for warm ups
Well, after wanting a warm lube for masturbation I put some baby oil in my hand, put the hair dryer on high-heat, and aimed it at my hand for a while.
When I applied the now hot baby-oil the effect was great, but sadly it wore off quickly and I had to re-heat.
This reminded me of PE, and warming up.
I now, sometimes, use the hairdryer when flaccid, to warm up before a session.
Try it, and let me know what you think of this method! All questions, comments, etc are appreciated.
