im (20F) too attracted to my boyfriend (20M)?

My boyfriend (20M) and I (20F) have been dating for about 5 months now after being best friends for about 2 years. He is the only person I can see a future with and he is the most wonderful person I've ever met. I've had a lot of sexual trauma in my life, but he makes me feel incredibly safe and he's the first man I've ever felt comfortable saying "no" to.

I'm not a super sexual person, I can usually (at most) have sex once a week. But this past week, I cannot get enough of my boyfriend. We've had sex the past four days in a row, sometimes multiple times a day. I usually hate giving head, but I initiated giving him head tonight and I absolutely loved it. I don't know what's going on but I'm ridiculously attracted to him. I didn't think I could be any more attracted to him (lookswise or personality wise). I'm not really sure what the cause of this sudden switch is and I was wondering if anyone else has experienced something similar.
