just another date night

so had a dinner date last night with some random from tinder, thought i was doing alright, just trying to keep it light and casual. but then we get back to my place and he's like 'lets do some roleplay,' and i'm not sure if im into that kind of thing yet. i did give him a key to the apartment b/c its late and i dont want to deal with cabs, so he just kinda took charge in there. ended up letting him tie me up a bit, never really tried anything like that before but surprisingly it wasnt bad at all. but now im not sure if this casual thing is working out as i thought, or if i should stick to my usual kind of dates without any extra stuff. whats normal anyway? lol
