I'm sorry you feel the way you do just know that your friend isn't really your friend they sound so unsupporative and mean. Please reconsider who is in your circle. Secondly i'm not trying to make you feel bad but you have to becareful who you sleep around with could you just never know, we all know that someone's sexual health staus is visable, so sometime you have to treat someone like they have hiv or etc. It's kind of like the first lockdown, everyone in the hospitals treated patients like they had covid as this was a safety precauction for staff and fellow peoples safety.
Lastly NEVER EVER make someone pressurise you into having sex without protection, it's your body and it's your choice what you want to do with it. Please learn from this, don't let it bring you down but instead let this be a teaching me to love yourself a bit more, but you first at all times and be selfish in that way. No one has control over you, you have the right to make choices. This world we live in is a creul one but at the same time we have to be careful of what we do, what we share with people and also our choices. I know you don't know me but please make a promise to yourself that you'll be careful in the future. I'm not trying to sound or be hard on you but i learnt my own lesson from using dating apps- i will cut my story short but i met a guy via a dating at just for a date nothing else and we had dinner at his, he S****** Abused me and i felt hopeless but i learnt from it and promised myself i will never meet a stranger indoors regardless of who they are. My advised to you moving on is take a sexual health screening test every 6 months just for your own safety, also if you get into a serious relationship with someone just try and find out about their sexual staus as this is also important. Learn how to love yourself a bit and don't let anyone make choices for you. Also listen to your gut and run with it, forgive yourself but learn from it. Overall it sound like you were pressrised and you didn't want to dispoint the person so you went for it instead of thinking about the consequences. I promise you it will get better and i'm sorry for what has happened to you please don't let it bring you down try and speak to a therapist or GP x Wishing you all the best xxxx
