i compartmentalise the feelings, i find the sex is better if i give at least a bit of a shit about the woman, however i can see them as just a fuck buddy, dont do it as much anymore but when i was in college i had a few women i would see on the regular and had some feelings for, i just knew i wasnt ready to settle and enjoyed no strings sex. the difficulty is keeping them close enough to want to fuck you without them also catching feelings a month or two down the line, in my experience women are far better at fuck buddies than guys but when they catch feelings they persue it alot more and dig into the feeings more. but that was just my experience
