Curious about using the aneros during intercourse.

Yes, you can use these devices with intercourse. Several threads and comments have been offered along this line over recent years as I recall. I would suggest trying out an Aneros on you own first and sounds like you already have. I don't nor have I seen any preponderance of other respondents to this type question say that it makes you ejaculate sooner or necessarily last longer with it. Perhaps with the "newness" of using a toy like this you get a bit more excited to where you ejaculate sooner as you've mentioned, but physically, it shouldn't really make you ejaculate sooner or last longer either way. As to having more powerful ejaculatory orgasms (and here we're talking about using an Aneros with conventional penile stimulated (i.e., intercourse) sex--not using the Aneros to learn how to have prostate orgasms which involves NO penis touching or stimulation at all) you usually will feel like the orgasm and ejaculation is stronger and more thorough because of the strong contractions your anus has when ejaculating squeeze the Aneros more firmly into your prostate gland while this is happening thus giving you an added internal sensation while the ejaculatory orgasm sensations are coming that makes everything seem more intense.

Comments over the years have discussed what size/shape massager to use when attempting intercourse with your wife. I'd suggest a medium to small sized model that is shaped in such a way that it "stays in" securely while you're in the physical activity of sexual intercourse and I'd suggest the best one for that would be the Helix or Helix Syn, or even the older MGX. These models are not so large that they hurt or squeeze uncomfortably inside during the ejaculatory contractions and they have a significant enough taper to their design where they "ride" in your anus so that they won't pop out during the physical activity of intercourse. Some guys note also that the large models almost block the flow of semen when orgasm and ejaculatory contractions come on and typically the larger models by their very design don't have much of a taper and will slide right out with physical activity, the Progasm certainly coming to mind in that respect. And right "during the heat" of sexual intercourse activity with your wife, it's not going to feel very good or impress her very much to have a big expulsion of your toy, which brings us next to the discussion of the issue of lubrication.

Many guys like minimal lubrication of the anus and toy but others like a fair volume of slippery lubricants (of whatever nature--there's discussion in abundance of lubrication preferences here) injected into the lower rectum and if you're doing that and have a sudden expulsion of your toy, or even just a nasty leak sneak out around it, it's gonna run down and depending on your intercourse position with the wife conceivably be a hygienic issue for her to contend with.

So, lots of issues to consider here and certainly trial and error gets most guys successfully through the significant pitfalls with this. But it's certainly nice, if you're trying to impress the missus with your performance while using your new toy, to make things be as nice for her as possible. Obviously, making the added pleasure of sex with these things something that she enjoys and maybe even takes a part in (like preparing your anus and inserting the toy, e.g.) adds to your enjoyment of the expanded sexual sensitivity you'll have with these things.
