Why is my boyfriend NOT pressuring me for sex?

I am 25 year old woman. I am a virgin and I have been seeing a 31 year old guy for 4 months now. He is amazing. I am a virgin and he just revealed to me he has slept with 20 women, I was floored. I am not judging but obviously he seems like a sexual guy but he is not pressuring me to have sex which I find odd. He treats me with respect and he doesn't act like something is lacking in our relationship. He says that he can control himself and that he respects my boundaries.

I am so puzzled, all this coming from a 31 year old grown man who has had 20 sexual partners and has been in relationships were sex was present. Why is he chill with me? I keep waiting for other ball drop. He spends all day at work and on the weekends he's with me. I know he isn't getting his bread buttered elsewhere.
