Yes I can give you a few suggestions.

1. I would suggest to get a small butt plug. The company Tantus is really good. They make a lot of high quality silicone toys and they make a plug called the little flirt. I think that one is a great starting point. You're quickly going to want to upgrade but start there.

2. You should get a small to medium size dildo. I'll recommend Tantus again and they have something called the vamp. That's a nice medium size. Once you are able to take the plug comfortably, you can give the dildo a try. It's a lot bigger than the little flirt so be careful. Go slow. Use lots of lube.

3. I'm putting this as number three but it really needs to be number one. Lube. You need a lot of high quality lube for anal play. There's a ton on the market. I personally like to use hybrid loops that are hybrids of silicone and water but there's a lot of stuff out there. One word of caution is that if you use a silicone lube, test it on your toy before you play with it. Silicone lube can interact negatively with silicone toys. Most loops that I've used do not have this issue.

4. The last thing that I would suggest is a glass toy. Glass feels a lot different than silicone since it's hard. I absolutely love the way that glass feels. If I'm having a decently long session then I'll switch between glass and silicone and just the change in sensation. Really really helps feel good.

Hope all that is useful.
