Is the guy i'm dating gay?

[twistedsista]

Hi, I'm 29 years old, i met this guy 31 yrs old and i like him a lot, he could be "The One" We've had like 2 dates in a space of 6 months (we have both been busy with work but have been in touch) anyway, he told me about a threesome he has had with his ex and it was a girl 2 boys one, during the threesome he said the guy gave him oral sex and he had enjoyed that and would I do something like that with him hypothetically speaking (confused.com i was then)
Then after on our other date we started to be more sexually open with each other (just talking about it) we haven't had sex yet. Just to see what his reaction would be like i asked him if he would ever dress up for me in a girly sexy underwear i said I think it would be fun, what did he do...? he went out brought one then took a picture with it and sent it to me (im still not sure what to make of that)
Then he started to be even more open and said that he would like it if i wore a strap on, and u know the rest of it (shocked!!!)
I'm very open minded and would have a relationship where we can both be adventures but this im thinking might a whole different ball game.....what do you guys and girls think? i really really like the guy but i cant get these things out of my head
