Big Brother's list of concerns might currently be sky high but an even more serious one just hit the sack.

In a conversation between Nengi and Kiddwaya, she revealed that she spotted 'cum marks' in the house while suggesting that some housemates may be having unprotected sex. She also questioned the possibility of female housemates getting morning after pills.

The housemates have repeatedly shared that there seems to be mounting pressure to get involved in a relationship in the house. So far, Kiddwaya and Erica have gotten intimate with Erica recently calling things off. Newly evicted housemates, Lilo and Ka3na also had their fair share of intense make out moments in the house.

Nengi's latest revelation comes as a surprise especially as the house has an ample supply of condoms.
