Does the guy affect orgasms?

Really weird question but let me tell you, my ex never made me cum. We were together for almost 2 years and the main focus was usually on him and he only fingered me by penetrating and I always got jumpy and pushed his hand away when he would try to touch my clit. I never came during sex either and trust me, he wanted to do it a lot, I didn’t as much. I was never really horny around him either and usually I never really wanted to have sex with him.

Fast forward to my relationship now. My boyfriend can get me horny just by looking at me a certain way or putting his hand on my thigh. When we first got together, this summer, I mentioned that it would be hard for me to get horny or even orgasm because that’s how it always was. I realized how easy it was for me to want it and eventually we started fooling around and he rubbed my clit and I didn’t even mind! Then he told me he would rather spend the night making me feel good instead of it being him getting off. So after playing around with me he apparently got me to cum like I would be dripping wet and I didn’t know I could even do that! Then he would always do that before we had sex so I could cum while he was in me because after I cum once, I can cum easier (both vaginally and with clit stimulation).

So my question is, does the guy make a difference with orgasms?
