i do remember some chicks in school that weed made horny,or so they said maybe they was just horny anyway,i knew a few of those too.
i think it may enhance the atmosphere or mood,sex is 90% in the mind so i can see it effecting alot of folks thinking,
smoke a fat jiont kick back see ya ol lady bend over picking up something the idea pops in ya head,the kids gone ,we can get naked and make the oh faces at each other , next thing ya know weed has led to sex.
so,mmm yea id say yea it does to some degree
peace
