I'm sorry this happened to you. This is pretty normal unfortunately, many men will prey upon young girl, or women, regardless of their age, how they meet them, or where they are. The same happened to me with my first boss, in his family home, during a barb b que, when i was 16 and his wife was out of the room. It happens all the time. If you drink more than one cocktail, or beer you're on your way to getting drunk, and if with any ne'er-do-well.. well on your way to being taken advantage of. If you sit down with someone that has the opportunity to put a pill in your drink that renders you "easy" that can happen to, whether it be in a bar , or in someones home who you think you can trust. Never leave your drink unattended. Another time, I was at a wake for our best friend Stan, who had died of leukemia at the age of 17. His father was from the old country, and as was his custom at least, offered the teenagers drinks. When this man's wife and children were in the other room, he tried to take advantage of me. It is in the nature of the beast I'm afraid. All you can do now is to truly understand the absolute harm you can come to when under the influence and cease and desist drinking to the point of ever remotely note being in complete control.
I think that you need a few older mentors. They say that a young person needs 4 or 5 adults in their life that they can trust to talk to. If you're in college, try seeing if there is a counselor you can talk to about the things that you felt the need to text this older man about. And even with a counselor, you have to hold them to a high professional standard and never put yourself in the position to be taken advantage of ( by anyone., EVER).
Have you had the vaccine for HPV? It's important that you do prior to having any sexual contact. HPV can, depending on the strain, cause cancer in later years, and most people have this disease unknowingly and can pass it to you. There are also people that have Aids and HIV that purposely transmit it to others. I don't want you to be paranoid. Obviously not all people are so inclined, but there are many that will to varying degrees take advantage of you if you allow them any chance at all.
The best thing you can do right now, is to pursue a degree or diploma and concentrate on a post secondary education, and if you're doing that now, Congratulations on making a fine decision for your future.
I'm not sure and you seem unsure of what happened. You are an adult who made a choice to drink alcohol with him. I don't know if you got turned on or if he was overly aggressive with you. It was inappropriate to say the least but you seem very unsure of the details. His touching your vagina and trying to put his penis in your mouth is not okay. If you didn't want that. I'm not sure you'll ever know the truth. You should cut off all contact. OR if you do feel he pushed himself on you, tell his wife, press charges, etc. For the protection of another young woman in his company. Unfortunately though, for many women who have bad relationships with their father, they are often sexually attracted to older men. This is a known pattern. He men can be pigs. So, I'm not sure what happened here but you can always explore it with a therapist. By the way, you experienced the danger of alcohol and drinking. Don't do it. It's the 'uninhibitor' and things like this are more likely to happen. good luck hon
