I need a second opinion.

My gf and I have stopped using a condom. We were fuckin doggy the other night and I pulled out and shot on her back. Probably the first time but never put much thought into it.

Then she got a little pissy with with me asking why I couldn't wait until she rolled over. When I tried to get an explanation she just shuts up and doesn't want to talk about it.

It was a real turn on doing it but I don't want to go through that again. Curious to know what people think. Does she like watching me cum? or having the feeling on her tits?

I'm just shocked because she has never really minded anything else. Last night we just had oral sex where I did all the work so and came in her mouth so haven't experimented much yet.

Thoughts?
