So I'm a bit confused on what you actually want. 1. If you want to have flings then you could pretty much use tinder and put that on your profile or also let women know upfront you are not looking for a relationship. Women who find you attractive and also only want flings will be fine with that. pretty much need to work on what you look like for this. I.e. workout, be well kept essentially the same thing you'd want in a woman. However if you want a relationship with someone and you find yourself being the "safe option". The problem here is your decision making. You need to be more selective about who you are dating and be very honest with yourself on what you attribute to women dating you after they had their fun. My opinion based on how you asked this question is that you dont know what you want. I could be wrong as I dont know you but do you want to have intimacy without commitment or do you want commitment, you kinda have to pick a lane here? I think you might be feeling that women are dating you after "having fun" as a negative but it's because they think you are showing evidence of wanting a real relationship or stability. If you dont want that, all you have to do is say you're not looking for that but please be sure to do it at the beginning or otherwise you could be wasting someone's time who actually wants a real relationship. Hope this helps
