Hi Claire,
Since you are coming across the same issue time and time again with guys that you meet on dating apps, make it a point to inform any guy that you conduct conversations with on a dating app in the future about your boundaries earlier on.
While you are still in the early stages of getting to know them, let them know about how you feel about kissing, having sex, or whatever else you have as a boundary if you were to start going out on dates with them.
It may seem a bit forward, but it is an excellent way to filter out the guys who don’t agree with your boundaries a lot earlier.
This way, you don’t find yourself putting out so much effort to go on multiple dates and share your life with them for weeks, only to have a falling out with them because they tried to get physical with you and you shut them down.
Get into the habit of being forward in this way. It will save you so much energy and prevent exhaustion. It may reduce the number of guys who decide to go out on a date with you, but at least, the dates you do get will be with guys who are in sync with your boundaries.
Quality over quantity should be your mantra from this point forward.
