It’s up to you really. I mean honest relationships are probably the best, but it’s not really a life changing lie you’ve told him. I imagine he’d only be annoyed that you lied to him in the first place. Although he might be happy you told him the truth in the end. However, telling him you’ve had sex ‘so many times’ might make him feel a bit more nervous about losing his virginity with you as he may feel you’re more experienced (I could be wrong here). But yeah, I can’t make the decision for you, it’s whatever you think will be best for your relationship. :)
It could just be that you’re not feeling quite as turned on by those particular positions. It’s not uncommon to lose ‘wetness’, I sure have and it’s quite annoying! If it happens again then try and get him to back to oral/fingering. I imagine it’s because you get more wet from clitoral stimulation (like most women), so you could even rub your own clit whilst he’s inside you.
If you’re comfortable with that then just go with it, do whatever feels good. I mean if you want to (and if he does) then maybe you could actually reach down in trousers and actually rub his dick without clothes. But if you’re not ready for that then just keep rubbing it whilst he’s still wearing clothes, that can be quite a big turn on!
I find giving tips on kissing quite difficult and it’s just one of those things that most people can do naturally. But I’ll give it my best shot!
I guess my main tip is to be slow with it, don’t just shove your tongue in the persons mouth and start waving it around in there, that is not sexy. Start by kissing normally, and if the other person seems ready then put your tongue a little bit inside there mouth, just gently nudging their tongue with yours. It’s almost like you’re massaging each others tongues, but smoothly.
Hope that helps!
Only be grossed out if you don’t like it. I mean it does sound odd that he pushes your tongue out. Maybe you should be more forceful (not in a rapey way haha) but try and do what you want to do as well.
