is it a normal occurence or is there more to it?

any opinions or advive will be greatly appreciated

Have a talk with him. I understand your position and of course the stakes are pretty high. But usually cuddling, sharing a bed, etc. are kind of not par for the course. If you shared a bed for brief traveling purposes to save money, that would be one thing. But that's not what this is.

So - talk. And maybe frame it initially in the context of friendship. "That was a great party last week (or whenever it was), eh?" I assume he'll agree although maybe he'll just claim he got overly drunk and it was horrible.

If his response is positive, then maybe try framing it as something like, "Weird we ended up in bed together. People are going to talk."

And see what the response is. Is it horror? Then back off. If it's defiant amusement (e. g. "Let 'em!"), then that's probably a pretty green light there. If it's in the middle, or if it's defiant but more like, "Well, I can't help it if they're nosy." (and then he changes the subject), you're still at a yellow light, I'd say.

For a green or a yellow light, maybe say something like, "I'm getting odd mixed signals from you." Again, you're being kind of coy about it because you don't want to lose the friendship. Don't be accusatory or anything, and be ready to back off with something like, "Well, it just seemed that way at the time. I don't know. Maybe it was the alcohol."

After that, don't push it unless it happens yet again, I'd say.

Good luck; it's a delicate balancing act. Not only are you trying to find out whether a relationship is at all possible, you're also trying to determine whether someone has the type of sexuality permitting such a relationship - and that might be something he hasn't even admitted to himself.

Be patient.

thanks for the advice, your right it is a hard position to be in as i also dont want him to feel uncomfortable around me. ill try and talk to him about it but no doubt ill just clam up as usual :/ ive never had as many mixed signals from one person. he hasnt been in any kind of relationship or intamacy with anybody for years. and theres no reason why he couldnt if he wanted to bare in mind hes 20. same for me not as long but still a long time
