Sex was great but...

I’ve been seeing this guy for two months now.

We act like we’re dating but we’ve never labeled it.

We had great sex

Sometimes we still do.

But I am starting to get bored with it.

Just today we did it this morning and I wasn’t that into it but wanted to do it, for him.

He turned me over, (doggy style) and I had my ass arched and all.

He was enjoying it but I felt bored.

Then he put his thumb in my ass.

It was really weird but I sort of enjoyed it.

Then he went too much and it hurt.

So I wasn’t really enjoying it much anymore.

I dont know how to get more into it.

How do I start enjoying sex more?

Any tips?

Like we switched it up a bit but then it kind of stopped.
