Gonna guess a typo and you mean you’re both inexperienced
Just run with it, you’ll both be on the same page and not know what you’re doing so enjoy it. Communication is key
Why you worried he’s gay? If he’s with you, I’m sure it’s not the case. But if stil not sure, then talk to him and explain how you feel, thoughts, concerns
You’ll be more ashamed if you don’t say something now, and let’s things go on and he turns out to be gay or if there’s something else gojng on rather than just being open and honest.
If you can’t trust him enough to be open and honest about this, then probs not the right guy
