If you don’t have enough time or money to buy condoms so that you can avoid an unplanned pregnancy, then you really don’t have enough time or money to have a child. Actions have consequences, and there is always another night.
If you really want to be intimate with someone and you don’t have the ability to find or purchase protection, consider engaging in a relatively low risk activity like mutual masturbation. If you have both been tested, and found negative, for STDs, you could also consider oral sex – but that is only a safe sex activity when it comes to preventing pregnancy. Most STDs can be spread from the mouth to the genitals and vice versa.
