Dating, struggling with initiation

I'm 22 male dating an Escort 26 female we have been together for a year, she's amazing, I love her to death. I love spending time with her, I love her smile, I love how sweet she is and supportive she is, I also love how she makes me feel. She's pretty successful and happy about where she is in life and I love that she owns it. This has nothing to with her but me, I just feel insecure. Not because of her line of work, not because she makes a lot of money, but I feel inadequate. I am sorry about my disgusting man things but I just can't bring myself to initiate sex even when I desperately want it, and she only does it maybe once in two-three weeks, and I do not ask for more, maybe because I let her have the lead or maybe because I don't want her to feel like she has to do work with me, I know logically that it's okay to ask and communicate. I feel like I can't expect her to do more that, and end up just hurting myself. She takes us out on dates and even supported me through some time where I had uncertain financial stress. I absolutely love and appreciate her for it. These are all amazing and nothing about that makes me feel insecure. Besides I'm in tech and soon to make big bucks and spoil her! But it's the lack of sex. I just don't want to be needy especially because she's already rocking, I don't want to be a nuisance. My masculinity feels very fragile. Have you talked to your boyfriend about something like this?
