Alcohol during a session is up to the participants obviously.
I'm a light weight drinker. When I do get a serious buzz going I'm told I'm a "fun" drunk by the ladies. However I've noticed that different types have different effects.
Beer-Makes me casual laid back cable-guy. Unfortunately to get a good buzz going I need to drink lots which means I'll spend more time peeing then humping.
Clear liquor- tequila, vodka. Me = Bulletproof porno star.
Dark liquor- whiskey, brandy. Headache that any physical activity sets off explosives in my temples. Even a mere hand job has me grabbing my head in pain.
Wine-sulfides are not my friend.
Champagne-despite it being sparkling wine it's like Viagra to me. Make it French bubbly and she better bring a friend (or two...or three....or four).
What are some of your poisons for naughty activity?
