Feels like imma explode!!!!

My bf has a chronic illness AND we are Long-distance. The last 2 times we have seen each other he has been really sick. It has been over a year since we've had sex of any kind. Im 30 and such a sexual person and idk wtd to doooooooo!! Truth is we never really had the same groove in bed anyway but his head game is SO strong... but obv when he is sick im not gonna ask for anything. The focus is completely on him and im so happy to bring him all the loving nurturing in my soul. I love our other forms of intimacy and this feels so selfish but tbh idk if I can do this... a life without sex... I've been taking care of my own business but it's just not the same. And what happens when its ttc? I'm so afraid and desperate....
