Nerves about sex

My boyfriend and I have been together for over 8 years now; however over the last few years I find I get so nervous about sex I put it off. I love it while I do it and wonder why I get so worked up about it when I’m in bliss afterwards. He never pressures and is so caring as well as supportive. I just feel so bad for not doing it as much as we both feel like it.... I do get super horny at all the most inconvient times to 😩

Does anyone else have this? And how do I move past this? I love him more than anything and just want to not get so stressed about it!
