this is going to seem really backwards but my boyfriend and I have been together for eight months and we're sexually active. problem is I like anal and he won't do it. I've done it in a past relationship and liked it. how do I convince my boyfriend to have anal sex with me?
For whatever reason, he has a hang-up about anal and simply doesn't want to do it. Nothing YOU do is going to make him change, but perhaps TIME will. It's not going to give you the immediate solution you want, and may never give it, but it's really the only option you have with him.
It's no different than a guy trying to convince a reluctant girl to try anal. Some girls simply aren't interested in even trying, and pushing them will only make them angry. But many will, over time, get curious, but you have to leave them alone and let them come to that on their own time.
I'm not into anal and most of my friends are not but I talked to one girl who loved anal and her boyfriend had never done if before. While they were having sex, she grabbed his penis and put it in her ass by herself. I guess he liked it and found it a turn on that she took control like that. He has liked it ever since so you should try that.
If he really feels uncomfortable with the idea, there may be nothing you can do. There are health risks to anal sex- plus there is the whole excrement factor- so it's not hard to understand why someone might be hesitant to try it. I suggest having a calm, undemanding discussion with him about why you like it and what can be done to help make it safe, clean and comfortable. Don't pressure him, just present your argument- and let him know how much you would enjoy it. Give him the opportunity to state his concerns, and ask him if there's anything new HE might like to try. If that doesn't do the trick, you may be out of luck. But there are always other things to try. Find something fun that you'll BOTH enjoy, or at least tolerate.
Maybe he would be willing to try anal play with a sex toy.
