Smoking has been proven to increase blood pressure and constrict blood vessels including the ones in the penis. A reduction of blood flow to the penis will prevent a man from getting hard and may even reduce sensitivity in the penis. Less sensitivity and reduction of blood flow due to smoking can be enough to cause chronic ED issues.
Lubrication at any point when touching anyone’s genitals is a must. Never touch a person’s most sensitive parts with dry hands, toys, or other genitals. Irritation and friction burns do not feel so good and without lubrication that’s exactly what you are doing to your partner. A good lube is a must-have in your nightstand, but not any lube will do. Buying lube is not as simple as one might think because there are so many different lubes to choose from, and all have both positives and negatives to consider before using.
