Yes, and no. Love doesnt give women orgasms, per se, but it can open an emotional door for them. Hopefully, love=comfort with them, so they will give more of themselves to the act itself. Chicks have a lot of different levels going on sexually. Chicks feel connection(or love, later on)/comfort/trust/animal attraction(lust)/physical touch/self esteem raising. Oh, and lets not forget your personnal skill, and compatability with each others bodies. (different girls like different shapes and sizes of cokks.). Guys are simpler. Its not that attraction itself gives bettor or more O's, but the more attraction, makes her get into it more, gets her wetter faster, helps her just 'let go,' so she will cvm more. Take the attraction, and comfort, and amplify it with the other things I mentioned above, and you've got fvck doll on your hands.
So, to answer your question, you can be lacking in the attraction, and it will take her longer to get into it, and not give herself fully, BUT...if you have good enough 'skillz,' her attraction level will skyrocket. No matter how unattractive you are, you will turn into the hottest thing the girl has ever seen, if you make her cvm ten times over. And Vice Versa. If you cant handle yourself in between the sheets, you attraction level will drop in her eyes.
