Biggest lie I’ve told my mom

Soo I’m 15 and April last year I went on a camping trip with my boyfriend, his sister, sisters gf and their friends. My boyfriend didn’t have enough money to buy an extra tent for me to sleep in so we told my mom I would share a tent with his sisters gf and he would share with his sister. What actually happened was my boyfriend and I shared a tent. I’m super paranoid about everything and I was so scared my mom would find out. Luckily she never did, plus his sisters gf told my mom her and I would share a tent. I actually ended up losing my virginity in a tent in the woods that night ! 😂 anyways, the time to go camping again is coming up and I’m kind of scared to lie again. This time around, my mom has this stupid boyfriend that is completely against teenagers dating. I feel ashamed having a boyfriend when I’m around him. I feel like he would question me. (My boyfriend and I have been together for about 2 years 3 months) should I go on the trip and lie or just not go? What would you do? Don’t criticize me please!
