2. Alcohol
Either you or she or both of you are drunk. How much is too much? 3 to 5 drinks can make you less wise in your decisions and less cautious. Consuming alcohol, you become more open for risky things, such as unprotected sex.
And you put yourself and the other person in danger of getting SDTs (HIV and other love bugs) or impregnating the woman. Such a situation is highly undesirable.
So, if you drink too much, make a rule to abstain from sex with a new girlfriend.
