There’s different ideas about how to create a raging boner all night, so you can fuck her brains out for 3 hours. Some people talk about nutritional supplements. Others talk about mind control of some sort or meditation.
Any recommendations?

By the way. The best lubrication I know of is coconut oil. Assuming both people like the taste of coconuts, it's more flavorful than the flavored lubs. So you can still go down on each other with out the weird chemical taste. Every girl i start seeing regularly, i buy them a jar to keep in their room. Then from time to time I flirt with them by texting a picture of the label. Or, I'll text them about having just eaten coconut pie, shrimp, donuts or whatever, and tell them I instantly thought about their vagina.

It's all about that testosterone bro. There are so many different things you can do/eat/drink/take/inject that can help you increase your test levels.

Some simple suggestions...

Heavy Lifting
Good diet
Proper sleep
No more porn
