Bangkok - A Thai women's foundation has issued a warning that drinking instant coffee or orange juice might lead to instant sexual arousal, media reports said Monday.

The Pavena Hongsakula Foundation for Women and Children issued the warning after hearing several accounts of young women losing their virtue after accepting potentially spiked instant beverages from men, the Bangkok Post reported.

One young woman, nicknamed Bee, told the foundation that a man she first met over the internet and then in person at his house offered her a cup of instant coffee he said was a new formula health drink.

"Bee drank the coffee and shortly afterward felt a surge of arousal and an instant desire for sex," said Pavena Hongsakula, who leads the foundation.

Bee slept with the man but her sudden loss of control raised her suspicions about what was in the instant coffee. She approached the foundation about issuing a warning to other women.

Pavena said her foundation had heard similar complaints about instant aphrodisiacs, including one from a bar hostess who was offered a cup of coffee from a patron and then felt a "sudden, unstoppable sexual excitement" that led her to have sex with the customer.

Besides issuing a warning to the public, the foundation has launched a search for the beverages to discover what ingredients are in them. (dpa)
