I’ve heard that drinking too much before sex can cause erection problems, but the few times I drank I didn’t find the experience pleasant or sexual at all. With weed there is this warm, pleasant, relaxing feeling, and it makes you horny. You’ll also find things amusing, so you’ll want to watch a funny movie. If you get too stoned and you can’t focus on anything because your mind is all over the place it might cause limp dick, but that hasn’t happened to me. If you aren’t used to weed I would recommend smoking a small amount, just enough where you feel it. It’s important to ask how strong it is first, because like alcohol, different strains of weed have different amounts of THC (the ingredient that gets you high), and some strains of weed and edibles are extremely potent. If you plan on watching porn after smoking, make sure you have everything all set beforehand. You’ll also get hungry, so pick out what to eat beforehand so you don’t make a stoned decision like an entire gallon of ice cream with hot fudge by yourself. Have your favorite things to drink nearby because the smoke will make your mouth dry. Eye drops are a good idea if you have to go out in public because your eyes will get bloodshot. Having sex or having fun by yourself on weed is beyond amazing, and the orgasm will blow your mind. There is no hangover like with alcohol, you just might feel a little bit tired the next morning, but a cup of coffee will snap you out of it.
