Feeling stressed and my anxiety is high

Im getting married on July 17th to the love of my life . It feels like lately we have been so stressed that we have fought quite a bit and have had some miscommunication that led to feeling crummy. Now fast foward to tonight , where we were trying to be sexy and he got a toy to masterbate with and then i kinda gave him a bj. Well then he wanted me to go deeper and I haven't been able to in the past, but I thought sure , maybe I could try to go deeper.

Well it made me run to the bathroom and throw up. After which he was in a bad mood and mad at himself for making me try and take him deeper . Then he said I dont have to give him bjs anymore and his toy he was masterbating broke. He said he is never going to buy another sex toy for himself and he is only going to focus on pleasing me . Like I dont know what to do .

I feel like i want him to enjoy sex too and my anxiety is thinking that without bjs or having more sex positions that work for us both, that maybe he will want someone different 3 or 5 years from now 🤔 I dont want his sex life with me to be miserable and I feel like i dont do it for him 😭

I really love him and I want him as my husband and father to our future kids, but i don't want him wishing he married someone else. What should I do ?
