So yesterday I (26f) met a guy (~30) on the tube - we made eyes across the carriage on northern line and I slipped my number into his hand on the escalator. He texted me and later we met for a drink. I wasn't even really planning to drink, but I have poor impulse control, and next thing i know we're back at his. Clothes are off almost immediately, and then we're getting into it, and he's sort of leading everything. I told him I was on my period, and he wasn't deterred, actually saying it was a turn on (never heard that before). I have a menstrual cup so there wasn't any mess, but it was still surprising.

Then at one point he says he has some toys he wants to try, and I seem pretty wild so would I be up for it. I figure, yea, why not. So he pulls out a blindfold and asked me to put it on, and back up against the wall. I heard a noise and then he got me to back up more and I felt something enter me, which I soon realised was a dildo with a suction cup. He asked me to suck him off during, and I took off the blindfold when I felt the dildo fall off wall, and looked to see that it was complete with balls. We returned to more "regular" sex and he choked me a little, stopping when it was too much, and always asking if I was OK.

Now, I've had mild bdsm sex before (choking, ties, spanking etc.), but only with a partner I had been with a little while and trusted. So I guess what I'm wondering, is isn't it a bit of a warning bell that this guy is asking me to do things just a few hours after meeting. He's nice, and I would want to see him again, but part of me worries that if that's his starting point then it'll get too intense for me. Thoughts?

TLDR: Had kinky sex (suction cup dildo choking) first night meeting a guy and worried it's too much.
