A lot of guys give out that kind of pressure without necessarily even saying it clearly - it's like an assumed thing with some (by no means all) men that if you show any kind of friendliness or even just not actively be hostile, it means you are available to be used for sex. There's also a heck of a lot of pressure to perform extreme sex acts from a number of blokes, having had their fantasies activated by the deluges of webporn, they want to play it out in real life. I've been around guys who were definitely claiming to be not satisfied with 'regular' sex and demanding something weird or hurtful or extreme. It's like an illness with some and there is definitely a need for recovery therapy from porn.
Has yours come through yet?
