First of all, if you cannot remember the details of what happened you should rethink your use of alcohol or drugs.
Often influenced by our environment we take things that are bad for our body and mind and push us to treat our own body in an unhealthy way. Having said that, not remembering the next day if you had sex or under what conditions, does not necessarily imply that it was in a condition of abuse, but you should think that other people take advantage of situations of alienation or unconsciousness to abuse others, so you should take extreme precautions if you reach those levels, not only for the sake of abuse but also for your own wellbeing and care.
Although we should always think about rejecting alcohol and drugs as an element of fun or rebellion for our own wellbeing, if someone abuses us if we are under their influence, it will never be our fault, it is always the abuser’s fault, regardless of the state the other person is in. Look for spaces you trust to talk about these situations with friends, family members or psychosocial professionals to find ways of socialising that are healthy and safe for you.
For more support and advice, you can also sign up to one of our Support Groups and share a space with other young people where we can look at how to take care of ourselves and our bodies.
You also should go to your nearest sexual health centre and speak with a professional about this further. It may be that you also need to get tested for sexually transmitted infections or if applicable take emergency contraception.
