If u don't wanna contact STDs, the best thing to do is use condom . . . Or abstain from sex . . . But since some married couples cheat on their partners, would u continue using condoms even after your wedding(and do it flesh to flesh only when u want to procreate)? . . . Or would u trust your partner enough not to cheat on u therefore doing it without condoms(risking ur health)? . . .
